In the case of beta particles, they have a smaller mass compared to alpha particles and they also travel at higher speeds. Both of these factors contribute to a lower LET for beta particles. The smaller mass means that beta particles have less momentum and are less likely to cause significant damage to the medium they pass through. Additionally, the higher speed of beta particles means that they spend less time interacting with the medium, resulting in a lower energy transfer per unit length.Rate this question:

Acute radiation syndrome typically occurs when the radiation dose exceeds
-
0.01 Gy (1 rad).
-
0.1 Gy (10 rad).
-
1 Gy (100 rad).
-
100 Gy (10,000 rad).
Correct Answer
A. 1 Gy (100 rad).Explanation
Acute radiation syndrome is a condition that occurs when a person is exposed to high levels of radiation. The severity of the syndrome depends on the dose of radiation received. In this case, the correct answer is 1 Gy (100 rad), which means that acute radiation syndrome typically occurs when the radiation dose exceeds 1 Gy or 100 rad.Rate this question:

When swipe testing a radiological source, what is the first step after you have prepared the field blank?
-
Apply a few drops of deionized (DI) water so the wipe is damp but not soaked.
-
Place a small X in pencil on the outer edge of the filter paper on the side to touch the source.
-
Check the filter paper with an ADM 300 with probe or an instrument capable of measuring beta/gamma to establish background reading.
-
In a slow back and forth “S” motion applying moderate pressure, swipe an area of 100 cm2.
Correct Answer
A. Place a small X in pencil on the outer edge of the filter paper on the side to touch the source.Explanation
After preparing the field blank, the first step is to place a small X in pencil on the outer edge of the filter paper on the side to touch the source. This is done to mark the specific area that will come into contact with the radiological source during the swipe test. By marking the filter paper, it ensures that the correct area is being tested and allows for accurate measurement of any contamination present on the surface.Rate this question:

What effect does the inverse square law have on a person’s exposure to radiation?
-
Moving away double the distance from a point source reduces the exposure by a factor of 4.
-
Moving away double the distance from a point source reduces the exposure by a factor of 2.
-
Moving away 1/2 the distance from a point source reduces the exposure by a factor of 1/2.
-
Moving away 1/3 distance from a point source reduces the exposure by a factor of 1/3.
Correct Answer
A. Moving away double the distance from a point source reduces the exposure by a factor of 4.Explanation
The inverse square law states that the intensity of radiation decreases as the square of the distance from the source increases. This means that moving away double the distance from a point source will result in the intensity of radiation being reduced by a factor of 4. This is because the intensity is inversely proportional to the square of the distance.Rate this question:
