WorksheetsUnconditional Release
Total questions: 10
Worksheet time: 5mins
Criteria to consider for the free release of materials include:
No fixed or loose surface contamination, Detectable Alpha contamination <100 ccpm
No fixed or loose surface contamination, Detectable internal activity <100 ccpm
No fixed or loose surface contamination, no fixed activity due to naturally occurring isotopes
No fixed or loose surface contamination, no radioactive labels or markings
Exit signs with tritium may never be free released.
True
False
Unconditionally release of security personnel weapons from the RCA should be documented on:
A Conditional Release Tag
An Unconditional Release Survey Log
Do not require documentation
A Baseline Survey Log
A Baseline survey should be performed
When tools issued from the hot tool room will be used in a high contamination area
When a clean special tool is brought into the RCA with the expectation for unconditional release
When tools issued from the hot tool room will be used in a locked high radiation area.
Naturally Occurring radioactivity is high enough to require the user to wear multiple dosimetry
An item which cannot clear a TEM shall be marked as radioactive material.
True
False
Items removed from pockets while in the RCA should be monitored using the TEM prior to leaving the RCA
True
False
Prior to unconditional release of a valve removed from the Waste Gas system
The valve must counted in and clear two distinct TEMs
The valve must be disassembled prior to placing in the TEM
The valve must be disassembled and surveyed with a beta sensitive instrument
The valve must be disassembled and sent for gamma spectroscopy analysis
The following isotopes may be considered Normally Occurring Radioactive Material
Cr-51, Mn-54 and Cd-109
C-14, Sr-89 and Sb-122
Ra-228, Th-232 and U-235
Fe-55, Co-60 and Zn-65
