Radiologic Technologist Practice Exam

What is the role of a dosimeter in a radiologic environment?

1. To assess image quality

2. To measure radiation exposure

3. To control x-ray tube output

4. To maintain equipment calibration

The correct answer is: To measure radiation exposure

A dosimeter plays a critical role in measuring radiation exposure in a radiologic environment. Its primary function is to monitor the dose of ionizing radiation that an individual, such as a radiologic technologist, is exposed to during their work. This is essential for ensuring safety and compliance with regulatory standards, as it helps to prevent excessive radiation exposure, which can pose health risks. Dosimeters are designed to detect and record the amount of radiation absorbed over time, allowing individuals and healthcare facilities to track exposure levels accurately. By regularly checking the readings from dosimeters, healthcare providers can implement safety measures, adjust working practices, and ensure that radiation exposure stays within safe limits. The other options, while important in a radiologic setting, do not pertain to the primary function of dosimeters. Image quality assessment involves analyzing the clarity and detail of radiographic images, controlling x-ray tube output relates to the operation and technical adjustments of the x-ray machine, and maintaining equipment calibration ensures that machines are functioning correctly but does not involve personal radiation exposure monitoring.
