Texas Industrial Radiography Gamma Practice Test

Which are common conditions that can lead to inaccurate dosimeter readings?

1. Extreme temperatures

2. Being stored improperly

3. Both A and B

4. None of the above

The correct answer is: Both A and B

Common conditions that can lead to inaccurate dosimeter readings include extreme temperatures and improper storage. Extreme temperatures can affect the chemical and physical properties of the dosimeter material. For instance, high temperatures may cause the dosimeter to respond to radiation differently, potentially leading to overestimation of exposure if the dosimeter’s calibration has not accounted for such conditions. Similarly, low temperatures can affect the mobility of the radiation-sensitive material, resulting in inconsistent readings. Improper storage can also significantly impact dosimeter accuracy. For example, storing dosimeters in areas with high radiation levels, humidity, or in proximity to other sources of radiation can cause contamination or false readings. Dosimeters need to be kept in controlled conditions, typically in a low-radiation environment, to ensure their reliability. Therefore, both extreme temperatures and improper storage are critical factors that can compromise the integrity of dosimeter readings, making them unreliable for accurate assessment of radiation exposure. This understanding emphasizes the importance of proper handling and environment for dosimeters in industrial radiography.
