Texas Industrial Radiography Gamma Practice Test

What types of radiation are Pocket Dosimeters designed to measure?

1. Gamma and X-Ray

2. Alpha and Beta

3. Neutron and Positron

4. Both B and C

The correct answer is: Gamma and X-Ray

Pocket dosimeters are specifically designed to measure high-energy radiation such as gamma rays and X-rays. These types of radiation are commonly encountered in industrial radiography, making pocket dosimeters essential for monitoring exposure levels to ensure safety in environments where these radiations are present. Gamma rays and X-rays possess the ability to penetrate materials, which is a crucial reason why the pocket dosimeter is calibrated to effectively measure these forms of radiation. The sensitivity and design of pocket dosimeters allow them to detect the ionization caused by gamma and X-ray radiation accurately. On the other hand, the other choices involve types of radiation that are not typically measured by pocket dosimeters. Alpha and beta particles, while significant in other contexts, are not the primary focus of pocket dosimetry because these particles have limited penetration power and different detection methods are usually employed for them. Neutron and positron radiation, found in more specialized fields, also require different types of dosimeters for accurate measurement, further highlighting why the focus of pocket dosimeters is on gamma and X-ray radiation.
