These tests verify that the equipment is still operating within an expected range of response and enable us to track performance while in use.
Quality Control
This is the smallest amount of activity that can be detected at a 95% confidence level.
MDA or Minimum Detectable Activity
Absorbed dose is expressed in terms of this
The rad
To exceed the limiting values set forth in 10 CFR 835 is to ____ __ ___
Violate the law
The RO-20 is a radiation detector used at PORTS that operates within which region on the Gas Amp Curve?
Ion Chamber
This is the radiation that enters the detector concurrently with the radiation being analyzed
Background
Maintaining these little metal circles in a clean manner increases reliability of counting equipment.
Planchets
This is the quantity of a single radionuclide that if inhaled or ingested in one year would irradiate a person to the limiting value of 5 rems
ALI
The federal dose limit for a radiological worker to the whole body is ___ rem/year
5
The Lud 12S that was used when the RCT surveyed Sanitary Trash is which kind of detector?
Scintillation or Excitation
Because we prefer to be right more than wrong, counting results are reported in a range that would be correct 95% of the time or at a 95% _____ ____
Confidence level
This is the level at which there is a 5% chance of calling a background level "greater than background"
Critical Detection Level
This is the science of dealing with the evaluation of the equivalent dose resulting from energy deposited within the body by radiation.
The federal dose limit for a declared pregnant worker is ___ rem per gestation period
0.5
What is the correction factor for Removable for the Lud 12 alpha (43-5)?
2
This format used when reporting uncertainty
x.xx ± yy
This phenomenon occurs on proportional counting systems when an alpha generated pulse is not large enough to exceed the upper discriminator and is counted as a beta.
Crosstalk
This is the analysis and measurement of intakes and doses from radionuclides in the human body.
Internal Dosimetry
Federal dose limits for minors and members of the public are ___ rem per year
.1
What is the beta correction factor for the Lud 2360?
8
By doing this, we can reduce uncertainty and improve statistical validity of samples.
Increase background count time
Which two counting systems used at PORTS contain discriminator settings to address Crosstalk?
3030 and Tennelec
Which type of bioassay measurement deals with urine and fecal collections?
In-Vitro
The administrative control level for a radiological worker at PORTS is _____ __ per year
500 mrem
Which semi-portable scintillation instrument used at PORTS uses Pulse Height Analysis?
3030
