David Shen | 7.1 | Proposed amendment: expand the list of exempted medical isotopes. - Gallium-68 and Fluorine-18 which are more common than 66 is missing from the new updated list. Also Ac-225 is starting to gain traction. |
David Shen | 10.13 Section 20, Radiation Survey Meters | Some licensees use direct reading dosimeters for other purposes such as Y-90 procedures (to know the injection is complete) or have them for other purposes not for dosimetry. If direct read dosimeters are to be added to this section, it should be clarified who is required to have them calibrated (i.e. industrial radiography, etc). |
David Shen | 10.20 SCHEDULE 1 (Section 1 and paragraph 38(1)(e)), Exemption Quantities | This is a welcomed change, some newer medical isotopes were being defaulted to lower limits resulting in a lower threshold for spill reporting. |
David Shen | Impacts attendus du DIS 24-01 | The changes as it stands would create confusion in terms of who would need to calibrate DRDs if they were not explicitly using them for the purposes of personal dosimetry. |
Jeff Dovyak RTNM, CRPA (R) Radiation Safety Coordinator Shared Health Manitoba | 7.2 Proposed amendment: reporting requirements for portal alarm monitors. (b) file an annual report with the Commission by April 30 that contains a summary of radiation detections for the calendar year before the date of the report; and
The existing annual reporting requirement in para 3(3)(b) provides no additional safety benefit, therefore, the CNSC intends to remove this reporting requirement to reduce the regulatory burden associated with shipments of unknown nuclear substances detected while in transport and that emit doses below 5 μSv/h. | No objection! I am in agreement with the 6th paragraph of Section 7.2, dropping the reporting requirement for an annual detections report – our Licensing Specialist was not sure where to file the last one that I submitted. |
Jeff Dovyak RTNM, CRPA (R) Radiation Safety Coordinator Shared Health Manitoba | 10.1 New and amending existing definitions: New definition of “uniformly distributed” The definition of exemption quantity (EQ) and of unconditional clearance level (UCL), both make mention of when the radioactive nuclear substances are uniformly distributed, however, the term is not defined. As such, the CNSC proposes to add a definition for “uniformly distributed”. | So what is the proposed definition? |
Jeff Dovyak RTNM, CRPA (R) Radiation Safety Coordinator Shared Health Manitoba | 10.13 Section 20, Radiation Survey Meters: The CNSC intends to amend this section to require that instruments used for radiation measurements, such as portable radiation survey and contamination meters and direct reading dosimeters must be calibrated within 12 months preceding their use. This amendment would help to clarify the requirement for persons to ensure that their instrumentation is calibrated prior to being used and aligns with section 25 of the Radiation Protection Regulations. | I am most concerned if not alarmed (no pun intended) at the idea of requiring annual calibration of Contamination Meters. This is potentially a huge, unnecessary burden on licensees and a waste of taxpayer money for publicly funded departments. If response to a check source is within expected limits annual calibration should not be required and it is likely that most licensees are doing Efficiency Measurements.
I’m uncertain about the propriety & necessity of requiring annual calibration for DRDs, if they are not used as the primary personal dosimeter; for instance if a worker is “badged” with OSLD but wears an EPD during pregnancy for additional surveillance. So while I do not necessarily agree with that, I’m not as opposed as I am for requiring annual Contamination Meter calibration. |
Jaime MacDonald | Section 10.12, dealing with Subsection 19(1) of the NSRDR | It will be important to clarify what is meant by 'all documents applicable to the radiation device'. Commercially-sensitive information is included with each application package for device certification to the CNSC. To say that a transferor must provide "all documents applicable" without a definition of just what that means may result in significant problems in interpretation, particularly with commercially-sensitive / proprietary information. If the specific types of documents that must be provided to a transferee are not defined, there may be significant impacts related to the protection of sensitive / proprietary information on design aspects of a certified device. |

Nicole Corrado | Corps principal | Comment on the main body of DIS 24-01 I am quite concerned with mandates for testing “fish tissue and other receptor species tests for exposure uptake”. As Canada is moving away from animal testing, this seems counterintuitive to include animal testing in a document to modernize practices, especially when there is no mention of phasing out and replacing the practice. Mining is harmful to all life, and to the planet. Forcing fish and birds to be exposed to the effluent, and cutting them up to test them for selenium and other pollutants is cruel and outdated. Canada is phasing out toxicity testing on animals. Please switch to animal free methods of testing effluent and other substances. For wild fish and birds, please stop lethal sampling and switch to humane non lethal bio monitoring like is done in humans. There are cruelty free modern alternatives to animal testing, including acute lethality testing. Cell cultures can determine effect of pollution for instance. Please reach out to antivivisection organizations regarding these tests, and lobby to change these outdated laws. Please stop the “acute lethality tests” on rainbow trout, three lined stickleback, and other fish species. These tests involve pumping effluents into fish tanks about once a month, and if more than half the fish die, the experiments are repeated. There are animal free ways to test for pollution. Any guardians of companion fish will test their tank using paper strips and test tubes. They do not deliberately expose the fish to effluents to see what happens. Please also end the practice of sublethal toxicity testing of effluent on baby fathead minnows and rainbow trout, and stop cutting up fish to test their livers for mercury. Please lobby the government to put an end to mandatory toxicity testing under the Fisheries Act and go cruelty free. Please only use non lethal sampling of wild fish, or take tissue samples from fish who were already caught for human consumption. Please do not kill or harm any animals for research. Many mining companies also kill animals as “pests”. Please only use non lethal methods of wildlife coexistence. Please only use humane non lethal methods to manage beavers and other wildlife. Killing beavers only leaves room for more animals to move in. And the traps kill many other animals. London Ontario and many other places manage beavers without killing. |

Sarah Ternan | 10.13 Section 20, Radiation Survey Meters | We would like to request clarification on the expectations of 'Calibrating' contamination meters. Currently Verification is performed on these Contamination Meters annually. Regulations requiring additional calibration is costly to public hospitals with already limited budgets for equipment. |
Randy Paura | Corps principal | The PTNSR Exemption for NORM Section 2(2)(a)(i) should be updated to align with the IAEA Regulations SSR6 as the current proposed wordings do not. Section 7.2 the proposed change to the PTNSR to remove the annual reporting should not occur. The CNSC advises the reporting does not provide any additional safety benefits is not correct. The CNSC paper submitted at the IAEA 18th International Conference on the safe transport of radioactive materials outlined the benefit of additional reporting was to determine the use of the exemptions and that the majority of alarms were from medical isotopes and NORM. |
Randy Paura | Impacts prévus | Section 4 of the PTNSR requires shipments to be classified in accordance with the IAEA SSR6 regulations. The IAEA SSR6 section 107 (f) regulations requires all NORM shipments that are mixtures to be classified by section 405 of the IAEA regulations. Section 2(2)(a)(i) of the PTNSR does not align with the IAEA SSR6 allowing for shipments at a higher activity than considered safe as outlined in the Coordinated Research Project Report Regulatory Control for the Safe Transport of NORM (IAEA TECDOC 1728) and incorporated into the IAEA SSR6. The CNSC does not regulate NORM Receiving facilities nor has the CNSC completed an assessment on NORM waste that would indicate 5µSv/hr is an exemption limit from the PTNSR. This is the limit for an exempted package. The CNSC will have no method of determining if NORM shipments have been properly classified as required by the PTNSR. This will create unsafe conditions as a result as the CNSC will not know if shippers are compliant with the PTNSR when no reporting occurs. Numerous Shipments of NORM fall under the PTNSR at 5µSv/hr when applying the exemption clauses. |
Jonathan Woodworth | NSRDR 10.16 Subsection 31(2), Obligations of Operators: | High praise for this change for operators to return dosimeters to the licensee within 30 days instead of 15 days. Dosimeter usage for industrial portable gauge operators can extend into isolated regions of Northern Canada, where meeting the requirement of 15 days has been all but impossible to meet compliance with the regulation, especially during winter months when transport in/out of a location is held for 1-2 weeks due to travel conditions. |
Jonathan Woodworth | NSRDR 10.18 Subsection 33(2), Obligations of Supervisors of Trainees: | A welcome change to have further regulatory guidance to support policies regarding this in written RPP's. |
Jonathan Woodworth | NSRDR 10.7 Subsection 8.1, Check Sources: | The proposed change for alpha emitting check sources from 3.7Kbq to 10Kbq is a welcome change. This would alleviate challenges with obtaining short lived alpha check sources before it's decay to below detectable activity, as often, for contamination (leak testing) monitors. |
Jonathan Woodworth | NSRDR 10.12 Subsection 19(1), Transfers | Regarding "all documentation associated with the radiation device be provided to the transferee". I would like to see support in regulation to the clarification of "all documentation associated with the radiation device". |
Cody Cuthill Normtek | Section 2(2)(a) | The PTNSR should be updated to conform with the IAEA regulations as it pertains to NORM. In particular Section 2(2)(a). Rationale: The PTNSR Section 2(2)(a) wording is confusing and not compliant with the IAEA regulations. The IAEA SSR6 outline that NORM can only be excluded in accordance with the 10 times rule only if in secular equilibrium in accordance with Table 2 and that NORM not in secular equilibrium must be calculated in accordance with the mixtures rule (Section 405), if they are to be transported in a safe manner. This came about as a result of the IAEA Coordinated Research Report to which Canada participated as outlined In TECDOC 1728 Safe Transport of NORM which states in the conclusion Section (7) the following; Screen shots from this document outlines it is not safe if the mixtures rule is not applied as follows: “(7) The need to apply paragraph 405 of TS-R-1 (2009) [13] to radionuclides that are not in secular equilibrium should also be clearer. This requirement is best illustrated by radium isotopes that have been separated from the decay chain of their parent. The exemption value of 10 Bq/g for 226Ra and 228Ra may be too high when the rule for mixtures is not applied. Recommendations from this Coordinated Research Project are reflected in the 2012 Edition of the Transport Regulations. These requirements, approved by the Board of Governors in March 2012 are now published." Furthermore, the Coordinated Research Project Report then provided an example indicating that the safe transport of NORM mixtures resulted in an exemption limit of 4.1 Bq/g was necessary to safely transport mixtures as noted below. “As the value of activity concentration for exempt material of TS-R-1, Table 2 e. g. for Th-228 activity concentration is by a factor 10 lower than this for the isotopes Ra-226 and Ra-228 as well as Pb-210 and Po-210, the limit of activity concentration decisively depends on the fraction of Th-228 (fTh228) in nuclides mixture, when applying the formula in para. 405. This issue is depicted at the following example: In the process of extraction of crude oil and natural gas, scaling takes place at the inner walls of the production pipes. The scales consist in most cases of barium sulphate in which radium isotopes co-precipitate, while the parent nuclides (U-228, Th-232) do not occur in the deposit. Accordingly. the secular equilibrium of the U-Ra decay chain and / or Th decay chain is disturbed. While Pb-210 and Po-210 are slowly re-growing from Ra-226 (the equilibrium is reached after about 100 years) Th-228 re-grows from Ra-228 with a so called “flowing equilibrium” within few years. Therefore, the fraction of Th-228 of the total activity is increasing with time (reaching equilibrium of 1.46 times Ra-228 activity concentration). The insertion of measured activity concentrations as provided in German report [3] into the formula of para. 405 leads to the following exempt activity concentration (sum activity): (fRa226 + fPb210 + fPo210 + fRa228) = 0.84 while fTh228 = 0.16 From this it follows that (0.84)/10 + 0.16/1 = 0.244, and next 1/0.244 = 4.1 Bq/g as exempt activity concentration, i.e. the sum activity of all relevant nuclides. This value can now be multiplied by 10 according to para. 107 f), while the specific activity of each radionuclide is given by its fraction.” As a result of the findings outlined in TECDOC 1728 Safe Transport of NORM the IAEA: SSR 6 thus stated shippers must calculate mixtures in accordance with Paragraph 405 of the IAEA Regulations. There is no option to classify by any other means as noted below. The PTNSR is not safe if they do not meet this requirement or classify mixtures in accordance with Para 405. The PTNSR is confusing as it requires transporters to classify NORM in Section 4 as per the IAEA Regulations (which requires NORM mixtures to be classified as per section 405) then contradicts this in its exclusion for NORM in Section 2 as they do not outline the requirement to classify mixtures as follows; "Exception (a) that is naturally Occurring, provided that it has (1) a specific activity that is less than or equal to 70 kBq/kg, or Shippers are left with a specific activity that corresponds to thirty year old legislation and does not address mixtures or what appears as a value determined from Table 2 of the IAEA Regulations but possibly calculated as per paragraph 405. Completely unclear.
“Specific activity of a radionuclide shall mean the activity per unit mass of that nuclide. The specific activity of a material shall mean the activity per unit mass of the material in which the radionuclides are essentially uniformly distributed. Note; the activity concentration and specific activity of a material are synonymous for the purpose of these Regulations.” The NORM exclusion in Section 2 does not comply with the IAEA regulations for this definition. Furthermore, this error causes problems in NORM industries as many provincial governments utilize the PTNSR in their regulations indicating that a facility cannot accept NORM governed under the PTNSR. Providing two options further create confusion and unsafe conditions. Normtek would recommend that the CNSC update clause 2(2)(a) to align with the IAEA Regulations by replacing clause (i) and (ii) to state; |
Cody Cuthill Normtek | General | The PTNSR proposed amendment 7.2 to eliminate the reporting requirements of unidentified loads less than 5 µSv/hr should be scrapped. Rationale: The CNSC proposes to eliminate reporting of unidentified loads less than 5 µSv/hr then advise under Section 7.6 of the proposed amendment to require improperly classified loads to be automatically reportable. Unidentified loads are improperly classified loads. In fact, most loads in the NORM industry are improperly classified loads as most within NORM industries have never even read the PTNSR and ship as NORM with no regards to classification. This has been brought to the attention of the CNSC as a result of a Dangerous Occurrence. When the CNSC excluded NORM from its mandate it did so without ensuring the provincial and territorial governments had the necessary training and experience to govern radioactive materials. To date still little regulations or oversite exist causing harm to the environment, workers and the public. The CNSC paper submitted at the IAEA 18th International Conference on the safe transport of radioactive materials outlined the benefit of additional reporting was to determine the use of the exemptions and that the majority of alarms where from medical isotopes and NORM as follows; “From the information collected over the years regarding these events, it was found that the majority of the alarms were caused by medical isotopes or naturally occurring radioactive materials” “Record Keeping and reporting of these events allow for the monitoring of the use of the exemptions, ensuring that the characterizations have been completed and that the nuclear substances have been safely disposed.”
