Technical Escort - Radiological Operations
Question | Answer |
---|---|
Negligible risk definition | Acceptable when the mission requires units to operate in a contaminated environment (significant advantages will be gained) |
Moderate risk definition | Acceptable in close support operations where troops must be able to continuously operate at full efficiency |
Emergency risk definition | Only acceptable in rare situations termed disaster situations (disaster situation outweighs the radiation emergency risk |
Periodic monitoring definition | Conducted at defined or predetermined intervals |
Continuous monitoring definition | Involves uninterrupted surveillance of the area |
What are the two types of monitoring techniques? | Direct and indirect |
Direct monitoring definition | Most precise monitoring technique |
Indirect monitoring definition | Lowers the risk of exposure to personnel |
What are the two types of radiological surveys? | Ground and aerial |
What are the advantages of ground surveying? | Done with own equipment, done in any weather, can be done at night and more accurate |
What are the disadvantages of ground surveying? | Higher risk of exposure rates, lack flexibility, lacks speed and requires more personnel and equipment |
When are surveys conducted? | After all fallout is complete |
What is the course leg technique? | Used to find the extent and intensity of radiological contamination |
What is the preselected dose rate technique? | Old contamination that is greater than the time of attack and neutron-induced radiation |
What must be determined before conducting any type of rad mission? | Turnback dose and turnback dose rate |
What are the two types of samples collected after a nuclear blast? | Refractory or volatile |
What is the composition of refractory samples? | Can handle temp over 1000 degrees F, non-volatile, glass, rocks, fragments of weapon/rocket fuel and heating fuels/fragments for the weapon |
What is the composition of volatile samples? | Dust, small debris within dirt, pass off readily in form of a vapor, evaporates easily and less likely to maintain its form |
What are ideal collection locations for refractory samples in urban environments? | Inside of cars and buildings (glass from windows) and top of buildings |
What are ideal collection locations for refractory samples in rural environments? | Melted material |
