Outcome 9 Flashcards
who regulates the use of nuclear substances in Canada?
Canadian Nuclear Safety Commission under the Nuclear Safety and Control Act
what are the 3 functions of the International Commission of Radiological Protection (ICRP)?
- to establish recommendations for radiation limits
- determine principals of radiation protection
- volunteers provide the research
what are the 3 functions of the International Commission of Radiation Unit and Measurement (ICRU)?
- set quantities and units of radiation
- develop constant charts (ex. exposure rate constant ERC)
- work with the ICRP to determine principles of radiation protection
which international body is part of the United Nations?
International Atomic Energy Agency (IAEA)
what are the 2 functions of the International Atomic Energy Agency (IAEA)?
- to inspect (world’s nuclear inspectorate)
- ensure that safeguarded nuclear material and activities aren’t used for military purposes
- promote safety and security: nuclear installations, radioactive sources, radioactive materials in transport, and radioactive waste
- promote science and technology: nuclear generation for electricity
- radiation transport recommendations
what are the 3 functions of the National Committee of Radiation Protection and Measurement (NCRP)?
- USA national recommending body
- inform public of radiation exposure and protection
- work with ICRP and ICRU to establish radiation quantities, units and measurements related to radiation protection
what are the three international bodies that establishes radiation quantities and measurements for radiation protection?
NCRP + ICRP + ICRU
what are the two important documents that our regulations are based on?
ICRP recommended dose limits reports #60 and #103
what are deterministic effects?
- effects that are CERTAIN to happen when thresholds doses are reached
how are deterministic effects affected by the doses?
severity varies with the dose
what are stochastic effects?
effects are NOT CERTAIN to occur
- probability of occurrence increases as dose increases
which biological effect has a small chance of occurring even at very low doses?
stochastic effects
Burns, cataracts, and radiation sickness are examples of what?
deterministic effects
cancer, genetic/hereditary effects are examples of what?
stochastic effects
what are the 5 license types?
- licence application
- licence to abandon
- licence renewal
- licence to amend, revoke or replace
- licence suspension
what is required in order to keep your licence?
all licensed areas need to submit an annual compliance report to cnsc
what requires a licence?
- areas that use nuclear substances or radiation devices above the exempt Bq quantities
*if you want to possess, use, transfer, store, import, export or service nuclear substances
what are requirements of the licence?
- posted in visible spot
- needs to be renewed every 2-5 years (?)
- have specific cnsc licence number
- photocopied and distributed to any supplier of radioactive material
on a licence application form, what is needed?
- applicant info.
- purpose of proposed licence
- radiation protection program
- radiation safety program policies and procedures
- specific requirements based on proposed licensed activity
what do you do when you apply for a licences?
- completed and signed application
- copy of current radiation safety manual
- copy of current radiation safety policies (ALARA, training, NEW designation, personnel dose rate monitoring, etc.)
annual compliance report needs to include radiation safety manual updates. t/f
true
when do site inspections occur?
- every few years or when significant changes to the license occurs
- new licenses
what are type I inspections?
In-depth inspection that includes observations, review of practices/procedures, staff interviews
what are type II inspections?
brief observation, measurements, and review of records
Licensee will be informed of upcoming inspection in writing. t/f
true
licensee will be given a list of non-compliances with a timeframe for remediation. t/f
true
which effects (deterministic and/or stochastic) does the EDL ensure that you avoid?
deterministic effects
- sets limits well below levels that cause these known biological effects
what do the guidelines of ICRP publications 60/103 consider regarding radiation protection and safety?
- considers standards of protection and benefit
- dose limits recommended follow ALARA
