Texas Industrial Radiography Gamma Practice Test

When working on a radiographic job-site, what additional device must be worn along with a pocket dosimeter and a film badge?

1. A survey instrument

2. An alarm ratemeter

3. A personal radiation "beeper"

4. An electronic radiation count-rate instrument

The correct answer is: An alarm ratemeter

In the context of radiographic job sites, wearing an alarm ratemeter is essential for immediate detection of radiation levels. This device provides audible alerts that indicate when radiation exposure reaches specified levels, thereby allowing the operator to take immediate action if necessary. The alarm ratemeter serves as a real-time monitoring tool that enhances worker safety in environments where radiation is present. The utility of having an alarm ratemeter alongside a pocket dosimeter and a film badge lies in the combination of devices that monitor and quantify radiation exposure, while also providing immediate alerts to any dangerous levels of radiation that may be present. The pocket dosimeter measures cumulative radiation exposure, while the film badge provides a record of exposure over time. However, they do not provide real-time alerts, which is where the alarm ratemeter becomes crucial. The other options may also play roles in radiation safety and monitoring but do not fulfill the same purpose as the alarm ratemeter in terms of providing immediate warnings to the worker. Thus, wearing an alarm ratemeter is necessary to ensure comprehensive safety measures are taken on-site.
