Week 2 review Dose Limits for Exposure to IOnizing Radiation

Question 1

Provides the most recent guidance on radiation protection

Answer 1

NCRP Report No. 116 (limitation of Exposure to Ionizing Radiation)

Question 2

Set of numeric dose limits that are based on calculations of the various risks of cancer and genetic effects to tissues or organs exposed to radiation

Answer 2

EFD limiting system

Question 3

A quantity that is used for radiation protection purposes to provide a measure of the overall risk of exposure to ionizing radiation. This quantity takes into account the dose of all types of ionizing radiation to irradiated organs or tissues in the human body. By including a specific weighting factor for each irradiated body part, EfD takes into account the chance of each part for developing a radiation induced cancer

Answer 3

EfD

Question 4

Leading international organization responsible for providing clear, consistent radiation guidance through its recommendations on occupational and public dose limits

Answer 4

ICRP

Question 5

Normally a medical physicist, health physicist, radiologist or other individual qualified through adequate training and experience who is designated by a health care facility and approved by the NRC and the state to ensure that a facility follows internationally accepted guidelines for radiation protection

Answer 5

RSO

Question 6

evaluates human and environmental exposure to ionizing radiation from a variety of sources, including radioactive materials radiation-producing machines and radiation accidents

Answer 6

UNSCEAR

Question 7

An annual EfD that provides a low-exposure cutoff level so that regulatory agencies may dismiss a level of individual risk as negligible

Answer 7

Negligible individual dose (NID)

Question 8

An upper boundary limit for radiation workers for yearly whole body exposure of 50 mSv

Answer 8

annual occupational EfD limit

Question 9

optimization for radiation protection

Answer 9

ALARA concept

Question 10

Describes the level of radiation exposures of a population or group from low doses of different sources of ionizing radiation

Answer 10

ColEfD

Question 11

Scientific journals published by the ICRP

Answer 11

Annals of ICRP

Question 12

Established by health care facilities to trigger an investigation to uncover the reasons for any unusual high exposure received by individual staff members

Answer 12

action limit

Question 13

Strictly an equipment performance standard

Answer 13

Radiation Control for Health and Safety Act of 1968

Question 14

Responsible for regulations concerning employees right to know about hazards that may be present in the workplace

Answer 14

OSHA

Question 15

Publications that list studies of biologic effects and associated risk of groups of people who were either routinely or accidentally exposed to ionizing radiation

Answer 15

BEIR reports

Question 16

An annual EfD that provides a low-exposure cutoff level so that regulatory agencies may dismiss a level of individual risk as negligible

Answer 16

FDA

Question 17

EfD recommended as an upper boundary dose of ionizing radiation that results in a negligible risk of bodily injury or genetic damage

Answer 17

EfD limit

Question 18

Agency that has the power to enforce radiation protection standards

Answer 18

NRC

Question 19

Lifetime EfD

Answer 19

cumulative effective dose (CUmEfD) limit

Question 20

A radiation quantity used for radiation protection purposes when a person receives exposure from various types of ionizing radiation. This quantity attempts to numerically specify the differences in biologic harm that are produced by different types of radiation. This quantity is the product of the average absorbed dose in a tissue or organ in the human body and the associated radiation weighting factor chosen for the type of radiation in question

Answer 20

EqD limit

Question 21

Indicates the ratio of the risk of stochastic effects attributed to irradiation of a given organ or tissue to the total risk when the whole body is uniformly irradiated

Answer 21

Tissue weighting factor (Wt)

Question 22

cancerous neoplasm caused by exposure to ionizing radiation

Answer 22

radiation induced malignancy

Question 23

Federal legislation requiring the establishment of minimal standards for the accreditation of educational programs for personnel who perform radiologic procedures and the certification of such individuals

Answer 23

consumer-patient Radiation Health and Safety Act (Title IX of Public Law 97-35)

Question 24

Applies to complete x-ray systems and major components manufactured after August 1, 1974

Answer 24

Code of standards for diagnostic x-ray equipment
