Employee Cert. Questions and Correct
Answers/ Latest Update / Already Graded
10 CFR 20
Ans: Volume 10, Part 20 of the Code of Federal Regulations
Activation Products
Ans: Non-radioactive material that becomes radioactive after
exposure to radiation in a nuclear reactor.
Acute Radiation Exposure
Ans: A large radiation dose received in a short period of time,
usually less than 24 hours
Administrative Guidelines
Ans: Dose administrative guidelines set by utilities. These
guidelines are lower than the federal limits and are used to help
control dose increase and prevent exceeding federal limits.

Ans: Radioactive material (contamination) can become
suspended in air. Work activities can stir up loose surface
contamination. In some cases grinding, sanding, and other
abrasive techniques can dislodge fixed contamination and cause
it to get into the air.
Airborne Radioactivity Area
Ans: An area in which airborne radioactivity exists in excess of
0.3 Derived Air Concentration (DAC) or 12 DAC-hours in a week.
This is the level of airborne contamination at which protection
is considered. Preventing airborne is always considered first.
Use of ventilation systems and HEPA filtration systems can
remove contamination from the air. Work practices such as
wetting surfaces while grinding and others can also be
effective.
ALARA
Ans: As Low As Reasonably Achievable. The purpose of ALARA
is to keep the dose of both the individual and group involved
with the performance of a task as low as reasonably achievable
and still get the task accomplished. This includes internal as
well as external dose.
