Radiological Detection - A4 Flashcards
In addition to the beta/gamma probe, what does the AN/PDR-77 contain?
An alpha “pancake” probe and an x-ray probe
Where can correlation/transmission factors for various materials be found?
GTA 03-06-008
How is data from the DT-236A collected?
By placement in the AN/PDR-75A
What is the difference between dose and dose rate?
Dose is the total cumulative intake since the reading started (odometer); dose rate is the quantity absorbed averaged over a set time span (speedometer)
What is the AN/VDR-2 capable of measuring?
Beta and gamma radiation
What is the primary difference between the AN/UDR-13 and AN/UDR-14?
The UDR-13 can only measure in cGy (centigray), while the UDR-14 can measure down to uGy (microgray).
How can we measure beta radiation using the AN/VDR-2?
Unshielded reading - shielded reading = Beta reading
What types of alarms can be set using the AN/VDR-2?
Dose and dose rate
What is the DT-236A?
A personal wrist dosimeter worn on missions by all personnel
How many batteries are required to turn on the AN/VDR-2? How many total can it hold?
1 9V battery to start, but can hold up to 3
What types of radiation can the AN/UDR-13 read?
Gamma and Neutron
What is attenuation?
The limiting of radiological transmission due to shielding
