Radiation Safety Flashcards
Deterministic effects
- threshold limits
- depends on doses
Stochastic effects
- cancer
- probabilistic effects
- no threshold, from a dose there is a risk when exposed to radiation
- severity of effects not related to dose
The system of radiological protection can only apply FULLY when the source of expose or pathways leading to the exposure can be?
Controlled
What two concepts help delineate the domain of radiological protection control
- exclusion
- exemption
When can a situation be excluded
When control is not possible - potassium -40 occurring NATURALLY in the human body
When control is obviously impractical - exposure to cosmic radiation
When does exemption take place
When controls are unjustified
Who is it up to to decide what is excluded or unwarranted
National regulators
What is the primary aim of the system of radiological protection
- protect the ppl and environment at an appropriate level against the detrimental effects of radiation exposure WITHOUT unduly limiting things humans wants to do associated with such exposure
What are the human health objectives of the system of radiological protection
- to manage and control exposures to ionizing radiation
