Area Monitoring
When we have a posted ARA, we are required to monitor this location. Periodt.
ARA Boundary
Which air sampler do we use to perform personal monitoring?
BZ
___ is the amount of a radionuclide that if inhaled or ingested would irradiate a person to their limiting value for control of occupational exposure.
Annual Limit on Intake (ALI)
Which side of the filter paper do you screen?
The side that is marked (inlet side)
Immediately Dangerous to Life and Health
This type of monitoring is often performed at or near the source.
Work Area (Inside Area)
If more than one person will be assigned to the PAM, which worker should wear it?
___ is the concentration of a radionuclide in air that if inhaled or ingested would irradiate a person to their limiting value for control of occupational exposure.
Derived Air Concentration (DAC)
When screening the Work Area lo-vol filter paper in a posted ARA during job coverage, compare the results to the _______ ________ and to the MUC of the required respiratory protection.
Limiting Condition
Thin amounts of almost any material can shield this type of radiation (paper, unbroken dead cell layer of skin, a few cm of air).
Alpha
If no airborne data exists for a job, we perform this type of sampling beforehand.
Baseline or characterization
What is the primary function of a BZ?
To characterize personnel exposure
What is the Fed Ted?
5 rem
Which type of radiation is not normally screened for air sample concentration, but must be considered when determining if an air sample is to be handled as RAM?
Beta
Because Uranium has a PEL of 0.05 mg/m3, which is the chemical concentration at which we must begin to use respiratory protection, we post an ARA at __% of the alpha DAC Value?
10(%)
An average of the area monitoring samples for a given job will be used to determine which Radiological Requirement listed on the RWP?
Bioassay Mode
BZs must be screened for a __ DAC-hr threshold.
4 (DAC-hr threshold)
Our PORTS alpha DAC Value is configured for which radionuclide(s)?
The Uraniums--234, 235, 238
Meter ___ is not considered for screening, only for field counting
MDA
If you were to stand in an area and breathe air that is at 1 DAC of any radionuclide for a working year, how much total exposure would you receive?
5 rem
This type of air monitoring is performed to provide surveillance of low concentrations of airborne radioactivity in various facilities.
Routine
If a BZ or BZs are used for personal monitoring for a job, what will the Bioassay Mode on the RWP be?
DAC-hr Tracking
Which physical control used at PORTS is built upon DAC values?
ARA Posting Limits
RP-PRO-00009 Appendix C is intended to help RCTs analyze air sample concentration using the instrument's run time and activity to determine what?
DAC
Which two RP programs complement one another to help us determine or verify personnel exposure at PORTS?
The Internal Dosimetry Program & the Air Monitoring Program
