Dose limits |
Radiation exposure limits that are pertinent to the protection of radiation workers
|
|
|
Stochastic effects |
Results of radiation exposure for which no threshold dose of radiation exist (e.g. cancer, general effects) |
|
|
deterministic effects |
Result of radiation exposure for which a threshold dose of radiation is assumed (e.g. cataracts, sterility) Also known as nonstochastic effects |
|
|
Radiation workers |
An individual who, through occupational risk, has a certain likelihood of exposure to ionizing radiation in the course of his or her normal duties |
|
|
Occupationally exposed workers |
Workers who have a significant potential for exposure to radiation in the course of their employment |
|
|
Occasionally exposed workers |
Workers whose duties May occasionally bring them into areas where radiation exposure may occur |
|
|
Cumulative effective dose (E) × age 10 mSv × 27 = 270 |
How do I calculate my dose limit? |
|
|
ALARA |
As low as reasonably achievable |
|
|
Protective device |
Items worn by the radiation worker to reduce exposure to radiation |
|
|
structural protective barrier |
Fixed x-ray facilities that are constructed of materials having effective x-ray attenuating properties and are of thickness sufficient to reduce exposures to desired levels Ex. Very thick walls with led |
|
|
Primary barrier |
A shielding structure that can be struck by the primary X beam exiting at the Xtube |
|
|
Secondary barrier |
Is shielding structure that can be struck by scattered and leakage radiation |
|
|
Protective device |
Items worn by the radiation worker to reduce exposure to radiation |
