Radiation Safety Policy Manual Part 1

to keep everyone safe and to set guidelines for ourselves

What is the purpose of the Radiologic Safety Policy Manual?

As low as reasonably achievable (ALARA)

Federal and state regulations require a written radiation protection program that includes provisions for keeping doses ____ ________ ____ ______________ _______________ (ALARA)

true

All radiation users shall be included in the program and shall be informed of the program and of their individual responsibilities. T or F

ionizing radiation

What is capable of producing biological effects that are detrimental to health?

true

It is assumed that any radiation dose, no matter how small, could produce some biological effect. T or F

unnecessary radiation exposures

The purpose of a radiation safety program is to prevent ___________________ _______________ ______________

stochastic or deterministic

Health effects from exposure to ionizing radiation may be __________________ or __________________

stochastic

Which health effect from exposure is random in an exposed population?

deterministic

Which health effect from exposure is predictable for an individual?

deterministic

_______________________ effects may be observed in an exposed individual when a large radiation dose that exceeds the threshold dose is received in a rather short time

stochastic

________________ effects are those that occur randomly in an exposed population, usually after a long latent period

short

Deterministic happens in a _________ time

long latent period

Stochastic occurs in a _________ ________ period

proportional

In Deterministic effects, the severity of the effect is _______________ to the dose

(for example: if the dose is high, the severity is high)

statistical basis

In Stochastic effects, since the effects cannot be distinguished form those that occur in a n unexposed population, the cause-and-effect relationship cannot be established on an individual basis, but ONLY on an ________________ basis

threshold dose

For Stochastic effects, it is assumed that there is no _____________ _________ and that the probability of occurrence is proportional to the dose

independent

In Stochastic effects, the severity of the effect is _______________________ of the dose

ALARA

exceed

individual dose limit

2 basic principles that apply to every individual that may be exposed to radiation:

- all radiation doses are to be kept __________________

- no dose to an individual shall be allowed to ________________ the appropriate __________________ ___________ ______________ for radiologic technologist set by Co-Lin which is set below the limit set by the NCRP

national council of radiation protection and measurement

What does the NCRP stand for?

ALARA principle

What principle is applicable even when the potential dose is well below the individual dose limit because it is assumed that some risk may be associated with any dose of radiation, no matter how small?

non-stochastic

What is another name for deterministic effects?

dose limits

What are intended to limit the individual's lifetime risk of stochastic effects and non-stochastic effects?

small chronic exposures

large doses

Dose limits are intended to limit the individual's lifetime risk of stochastic effects from _______________ _____________ exposures, as well as to prevent non-stochastic effects from ________________ doses

true

Radiation workers dose is higher than non-occupational users because of their work. T or F

true

Dose limits are based on the philosophy that dose limits are different for radiation workers and non-occupational users. T or F

effective dose equivalent man

Radiation dose limits are specified as a quantity called the ______________ ___________ _________________ _______

rem

SI

sievert

The effective dose equivalent man is specified in traditional unit of ________ and ________ unit of _____________

effective dose equivalent

What is the dose to the whole body that comes from penetrating x-rays that would impart the same lifetime risk of detrimental health effects as the sum of the actual doses to all tissues and organs of the body from all types of ionizing radiation?

rem

The Copiah-Lincoln Community College expresses all doses and limits in ___________

NCRP

Who sets the dose limit measurements?

NRC

Who mandates specificalities on our exam rooms and make sure certain thickness are equivalent?
