- RPM-1 Each permit holder shall establish, implement and maintain procedures designed to ensure that all occupational radiation doses are as low as reasonably achievable (ALARA).
- RPM-2 Each permit holder or their designate shall ensure the dose rate at any occupied location outside the storage area, room or enclosure resulting form the substances or devices in storage does not exceed 2.5 uSv/hr. Appropriate shielding shall be interposed, and in whatever quantity in order to reduce field strength to a level below 2.5 uSv/hr.
- RPM-3 The permit holder shall ensure that all persons working with radioisotopes under authority of their Internal Radioisotope Permit are properly trained in safe handling, storage, and disposal procedures, and are informed of the associated hazards of radioactive materials.
- RPM-4 All undergraduate students participating in experiments or procedures using radioactive materials shall be closely supervised and instructed in safe handling and disposal procedures.
- RPM-5 The permit holder shall instruct authorized users under their authority of any specific hazards associated with a particular procedure within their laboratory.
- RPM-6 The permit holder shall permit any authorized user under their authority to attend any radiation protection courses offered by the University in cases where instruction is deemed necessary to ensure the safety of such users. Attendance at such sessions shall be considered paid time.
DOSIMETRY
- D-1 The permit holder or their designate shall ensure that all authorized users are provided with a thermoluminescent dosimeter where required under page 2 of the Internal Radioisotope Permit, and that such dosimeters are used properly by authorized users.
- D-2 Any authorized user that becomes pregnant shall forthwith inform the permit holder and EHSS. The authorized user shall participate in any additional dosimetry programs EHSS deems appropriate. The authorized user and the permit holder shall comply with any additional protective measures with may be prescribed, and may include a modified work program for the duration of the pregnancy.
- D-3 Authorized users conducting radioiodination procedures shall participate in monitoring programs. The permit holder or their designate shall inform EHSS of their intent to carry out such procedures.
- D-4 The permit holder shall ensure that nay person who handles a container which contains more than 50 Mbq of phosphorous 32, strontium 89, yttrium 90, samarium 153 or rhenium 186 wears a ring dosimeter. The dosimeters must be supplied and read by a dosimetry service licenced by CNSC.
SIGNING/POSTING
- SP-1 All areas in a radioisotope laboratory where isotopes are used or stored shall mark such areas with radioactive marking tape. Waste receptacles not destined for municipal landfill shall be marked.
- SP-2 A radiation warning sign shall be mounted on all doors leading into radioisotope
- laboratories where there is a radioisotope in a quantity greater than 100 EQ, or there is a reasonable probability that a person will be exposed to an effective dose rate greater than 25 uSv/hr.
- SP-3 The appropriate CNSC Basic or Intermediate Level Laboratory Rules poster shall be posted in each room where radioisotopes are used or stored. The name and phone number of the responsible contact person shall be entered in the space provided. The permit holder and all authorized users shall comply with these Rules.
PURCHASE, RECEIPT & SHIPMENT OF RADIOACTIVE MATERIAL
- PRSRM-1 All radioactive materials shall be ordered using the Radioisotope Purchase Requisition form. The permit holder shall follow the Procedures for Ordering Radioactive Material.
- PRSRM-2 Each Radioisotope Purchase Requisition shall have all the required information, be signed by the permit holder or their designate and be approved by EHSS prior to ordering.
- RSRM-3 All shippers' declarations, packing slips and accompanying documentation shall be forwarded to EHSS.
- PRSRM-4 All radioactive materials offered for transport shall be directed through EHSS.
- PRSRM-5 The permit holder shall communicate his/her intent to transfer radioisotopes to another permit holder, institution, or destination outside Canada, to EHSS. The permit holder shall not transfer isotopes until approval is granted by the EHSS. The permit holder shall comply with any requirement imposed by EHSS.
- PRSRM-6 The permit holder shall inform EHSS of the receipt of radioactive materials from another permit holder, institution, or importation across an international border.
INVENTORY & DISPOSITION
- ID-1 The acquisition, use, and disposal profile shall be documented on Form 2: Inventory of Use and Disposition. All information on Form 2 shall be provided. A copy of Form 2 shall be forwarded to the Environmental Health and Safety Service upon total disposition of the radioisotope. The permit holder shall retain such records for three (3) years.
- ID-2 Waste disposal shall be in accordance with the procedures outlined in the Radiation Safety Manual or any other practice agreed upon by the EHSS.
CONTAMINATION MONITORING
- CM-1 Each permit holder or their designate shall initially construct a laboratory plan of all rooms under the exclusive control of the permit holder where isotopes are used, and shall specify on the plan, the exact location where isotopes are used, stored, or disposed of within that laboratory. The plan shall be updated to maintain ongoing accuracy.
- CM-2 Contamination monitoring shall be conducted weekly, in the case of a Basic Level laboratory, or, immediately following procedures using quantities in excess of 5 ALI. Results of monitoring shall be documented on Form 3. Results of Contamination Monitoring-Monthly Log and shall be cross-referenced to the laboratory plan. Results shall be retained for a period of three (3) years.
- CM-3 Where results indicate levels of contamination in excess of 3 Bq/cm2 for all class A radionuclides, 30 Bq/cm2 for all class B radionuclides, 300 Bq/cm2 for all class C radionuclides averaged over an area not exceeding 100 cm2 , the responsible individual shall forthwith decontaminate such areas, and shall document results after decontamination on Form 3.
- CM-4 Monitoring shall be conducted through wipe testing, OR, if a contamination survey meter is available, and its detection efficiency is a minimum of 20% for the isotope beingmonitored, may substitute for wipe testing. The type of monitoring shall be documented on Form 3.
- CM-5 The permit holder or their designate is not required to conduct monitoring where the inventory indicates that isotopes have not been used in the previous seven calendar days. The contamination monitoring record for that shall be marked "no isotope use".
REPORTING
- R-1 The permit holder shall inform EHSS of his/her intent to discontinue radioisotope use whether permanently or temporarily (i.e. sabbatical). The permit holder shall comply with any requirement imposed by the EHSS regarding decommissioning, disposition of retained records, and disposition of existing stocks of radioisotopes.
- R-2 The permit holder shall forthwith report any required modifications to the Internal Radioisotope Permits.
PROHIBITIONS
- P-1 The permit holder shall not accommodate for the storage or consumption of food, beverages; or equipment for the preparation of food or beverages; cigarette smoking, or the application of cosmetics within areas where radioisotopes are used or stored.
- P-2 The permit holder shall not transfer radioisotopes to a person not authorized to receive such isotopes, and includes individuals having had such privileges suspended by way of sanction under statutory law.
- P-3 The permit holder shall not permit under-aged individuals into areas where radioisotopes are used or stored.
- P-4 Radioisotopes shall not be transported in a private motor vehicle on a public road, either by the permit holder, his/her designate, or by request to University transport.
