NCRP report no. ( limitation of exposure to ionizing radiation) - Answer✔Provides the most
recent guidance on radiation production
EfD Limiting system - Answer✔Set of numeric dose limits that are based on calculations of the

hazards may be present in the workplace
BEIR Reports - Answer✔Publications that List studies of biological effects and associated risks of
groups of people who were either routinely or accidentally exposed to ionizing radiation

Cumulative effective dose limit(CumEfD) - Answer✔Lifetime EfD
EqD limit - Answer✔a radiation quantity use for radiation protection purposes when a person
received exposure from various types of ionizing radiation
Tissue Weighting factor (Wt) - Answer✔Indicates the ratio of the risk of stochastic effects
attributable to irradiation of a given organ or tissue to the total risk when the whole body is
uniformly irradiated
Radiation-induced malignancy - Answer✔Cancerous neoplasms caused by exposure to ionizing
radiation
Consumer patient radiation Health and Safety Act (title IX of public law 97-35) -
