Dose Limits Flashcards
T/F: Effective dose limits can be either whole body or individual organ doses
True
Responsible for workplace monitoring
OSHA
Controls possession, use, and production of atomic energy; oversees nuclear energy industry
National Regulatory Commission (NRC)
Responsible for design and manufacturing of x-ray equipment
FDA
Responsible for environmental monitoring
Environmental Protection Agency (EPA)
States that have agreement with NRC to assume responsibility for enforcing radiation protection regulations through their health department
Agreement States
Cumulative Effective Dose
10 mSv x age (years)
Annual occupational effective dose limit
50 mSv (5000 mrem) / year
Pregnant radiation workers exposure limit
0.5 mSv (50 mrem) / month; 5.0 mSv (500 mrem) for entire pregnancy
Working in conjunction with their partners in other agencies, the FDA intends to take action to
1. promote safe use of medical imaging devices.
2. support informed clinical decision.
3. increase patient awareness.
1, 2 and 3
T/F: Medical imaging personnel absolutely never receive equivalent doses that are close to the annual occupational effective dose limit.
False
A radiation safety officer in a health care facility must have sufficient authority, organizational freedom, and management prerogative to
1. identify radiation safety problems.
2. initiate, recommend, or provide corrective action.
3. stop unsafe operations involving by-product material.
4. verify implementation of corrective actions.
All of the above
Determine the cumulative effective dose (CumEfD) limit to the whole body of an occupationally exposed person who is 46 years old
460 mSv
Effective dose (EfD) limits may be specified for:
a. whole-body exposure.
b. partial-body exposure.
c. exposure of individual organs.
A, B, and C
The primary function of the Nuclear Regulatory Commission (NRC) is to
oversee the nuclear energy industry
Upper boundary safe radiation exposure limits for occupationally exposed persons are associated with risks that are similar to those encountered by employees in other industries that are generally considered to be reasonably safe. These industries include
1. manufacturing.
2. trade.
3. government.
All of the above
the current method for controlling the risk of biologic damage to radiation workers and the general public from radiation exposure
The effective dose limiting system
The ALARA concept adopts an extremely conservative model concerning the relationship between:
ionizing radiation and potential risk
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 an employee’s “right to know” with regard to hazards in the workplace
All of the above
