The essential concept underlying radiation protection is that:

Which of the following are functions and/or responsibilities of the United States Occupational Safety and Health Administration (OSHA)? 1)Functions as a monitoring agency in places of employment,predominantly in industry 2)Regulates occupational exposure to radiation through Part 1910 of Title 29 of the U.S.Code of Federal Regulations (29 CFR 1910) 3)Responsible for regulations concerning the "right to know" of employees with regard to hazards that may be present in the workplace

Determine the cumulative effective dose (CumEfD) to the whole body of an occupationally exposed person who is 34 years old.

When whole-body occupational exposure is controlled by keeping the effective dose (EfD) well below the upper boundary limit,the possibility of inducing stochastic effects of radiation is:

The ALARA concept presents an extremely conservative model with respect to the relationship between:

The annual occupational effective dose (EfD) limit does not include: 1)personal medical radiation exposure from an imaging procedure. 2)natural background radiation exposure. 3)radiation exposure received on the job.

To define ALARA,health care facilities usually adopt investigation levels,defined as Level I and Level II.In the United States,these levels are traditionally _______ to ______ the applicable regulatory standards.

Which of the following are responsibilities of a health care facility's radiation safety committee (RSC)? 1)Assist in the development of the radiation safety program 2)Provide guidance for the radiation safety program 3)Facilitate the ongoing operation of the radiation safety program
