Week 2 RPMR Flashcards
This is the current method for assessing radiation exposure and the risk for biologic damage
EFD limiting system
the formula for efd
Radiation W1 x Tissue W1 x Absd. Dose
efd is used for what
to minimize risk of harmful effects
what attempts to factor in the dose based on different types for radiation exposure
Equivalent dose
What is the formula for EqD
Absorbed dose x Radiation W1
EqD is helpful in what
calculating EfD
What does ICRP stand for
International Commission on Radiation Protection
What does NCRP stand for
National Council on Radiation Protection
What does UNSCEAR stand for
Un Scientific Committee on Effects of Atomic Radiation
What does NAS/NRC-BEIR stand for
National Academy of Sciences/National Research Council Committee on Bio. Effects of Ionizing Rad
What is considered the International authority on the safe use of radiation
ICRP
When was ICRP started and why is it the leading organization
1928
clear guidance on radiation protection standards
IRCP only makes what and doesn’t what?
recommendations and is not an enforcement agency
what is a nonprofit corp charted by congress in 1964
NCRP
NCRP determines what
the way ICRP recommendation are used in the US
NCRP is not what
an enforcement agency
UNSCEAR was established when and plays a prominent role in what
1955
the formation of radiation protection guidelines
UNSCEAR evaluates what
human and environmental exposure to various sources of radiation, including radioactive materials and radiation accidents
NAS/NRC-BEIR is what and isn’t
another advisory group that reviews studies of the biological effects of radiation and risk assessment
an enforcement agency
US Regulatory Agencies
NRC AGREEMENT STATES EPA FDA OSHA
what does NRC stand for
Nuclear Regulatory Commission
What does EPA stand for
Environmental Protection Agency
FDA stand for
Food and Drug Administration
OSHA stand for
Occupational Safety and Health Administration
NRC formerly known as the _ and can control what
AEC
possession and use of atomic energy
NRC has the power to what
enforce radiation protection standards
NRC does not what
inspect imaging facilities
Agreement states have entered into an agreement with whom and why
NRC
to enforce radiation protection standards
how many states are Agreement states
most of the 50 states
when was the EPA established and by whom
1970
President Nixon
The EPA is responsible for what
the protection of humans and the environment
FDA is involved in what
the regulation of electronic products and x-ray equipment
FDA will conduct what
onsite inspections of x-ray equipment
compliance with FDA standards ensures what
proper radiation safety
OSHA is what type of agency
monitoring agency in places of employment
OSHA regulates what
employee’s “right to know” regarding to hazards in the workplace
Employers are required to provide what
training and written information on workplace hazards
NRC mandates what
that facilities providing imaging services must have a radiation safety program
Effective radiation safety programs ensure what
the adequate safety for patients and radiation workers
Radiation protection
ALARA concept
ALARA presents a what
conservative model for radiation protection
ALARA follows what response
Linear Non-Threshold Response
EfD sets what
occupational and non-occupational limits
upper boundary dose for radiation resulting in somatic or genetic damage
EfD limits
radiation protection has 2 objectives
- to prevent non-stochastic effects from occurring
2. to limit the risk of stochastic responses to radiation exposure
federal law requiring minimum standards for accreditation and education for persons administering radiologic procedures
consumer-patient Radiation Health and Safety Act of 1981
what provides the most recent guidelines for radiation protection
NCRP
