ARRT Level 1 Module 6 JKO questions &
answers
Annual limit on intake - answer What is the quantity measurement
of a single radionuclide which, if inhaled or ingested in one year,
would irritate a person, represented by reference man to the
limiting value for control of the workplace and has a unit in
activity?
0.8 minutes - answer A worker group has a total exposure limit of
5 mR. The group must perform work in a radiation area at a 2
meter distance from a 5 curie point source emitting a single 0.662
MeV gamma ray with an abundance of 85%. What is the stay time
of the workers?
0.5 CEN - answer Which formula is used to determine the gamma
radiation field intensity in R/hr at one meter from a radioactive
point source?
Derived air concentration - answer What is the quantity
measurement obtained by dividing the annual limit for any given
radionuclide by the volume of air breathed by an average worker
during a working year and has a unit of activity per volume?
Mobilizing agents - answer What is the term used to describe the
compounds that increase in natural turnover process thus
releasing some forms of radioisotopes from body tissues?
