Any Rad Worker, by virtue of their training, may post radiological areas and/or move radiological postings.
What type of radiation does protective clothing protect you from?
Beta and Gamma
All Types
Alpha
None of these
When wearing full PCs, workers may not choose to wear latex gloves instead of rubber gloves.
When removing protective clothing (hood, coveralls, cloth glove liner, rubber gloves, shoe covers, rubber overshoes), which one of the following items is removed first?
Rubber overshoes
Gloves
Hood
When donning a single set of protective clothing, what is the correct position of the shoe cover (bootie)?

After exiting a Contamination Area, what type of survey should you perform to determine whether or not you have contamination on you?
Internal contamination survey
Airborne survey
Indirect survey
Direct survey
It is not common practice in the industry for a PC hood and surgeon's cap (skull cap) to be used interchangeably, based on the preference of the wearer.
What level of protective clothing is typically required for Rad Workers in a Contamination Area?
Scrubs
Full PCs
Partial PCs
Double PCs
When using protective clothing, the order in which you remove them is more important than the order in which you put them on.
What level of protective clothing is typically required for Rad Workers in High Contamination Area?

You are working in a room within the RCA. You see what appears to be white powder on the valve bonnet. You should think:
Neutron emitters may be present
It is residue from stem packing
It is likely contaminated
It may be cocaine
When taking contamination surveys, smears typically be taken on floors and on equipment, pipes, or structures.
Background radiation dose is never subtracted before recording dose rate readings on the survey map.
What instrument data is typically recorded on a contamination survey map?
ID number
Calibration data
10% of low scale
Response check date

Rem/hr
mR/hr
R/hr
None
An asterisk on the radiation survey map indicates what?
Hot Spot
Beta Reading
Contact Reading
Neutron Reading
Which of the following situations would likely involve beta radiation?
A "hot spot" survey of an elbow on a pipe containing reactor coolant?
A routine "general area" survey of a heat exchanger room in the RCA
A "general area" radiation survey in the reactor building of BWR immediately after reactor shutdown.
A radiation survey of a reactor coolant ion exchanger resin spill in the rad waste building
