Radiologic Technologist Practice Exam

Which of the following attributes do personnel monitoring devices include?

1. They must not be susceptible to environmental conditions.

2. Devices are designed to record only small exposures.

3. The device must reflect human tissue absorption characteristics.

4. 1 and 3

The correct answer is: Devices are designed to record only small exposures.

The appropriate choice reflects the correct attributes of personnel monitoring devices. Such devices are indeed designed to record radiation exposure, and because they serve this specific function, they must accurately indicate the level of radiation that personnel have been exposed to over a period of time. The correct attributes of personnel monitoring devices include their ability to reflect the absorption characteristics of human tissue. This is fundamental because different types of tissues in the human body absorb radiation differently; thus, a device that accurately mirrors these characteristics is essential for assessing potential biological effects of radiation. Monitoring devices are also ideally designed to be robust against environmental conditions to ensure their readings remain consistent across different settings, but this is not universally applicable to all monitoring devices. In terms of recording only small exposures, it's important to note that while these devices can measure smaller doses, their purpose extends beyond just capturing small exposures to providing a comprehensive overview of a person's radiation dose history. Therefore, the attributes highlighted in the correct option are vital for ensuring that exposure measurements are reliable and reflective of actual biological impact.
