Radiation Safety Practice Exam

Which term describes the measurement of the dose equivalent to biological tissue?

1. Roentgen

2. Gray

3. Sievert

4. RAD

The correct answer is: Sievert

The term that describes the measurement of the dose equivalent to biological tissue is Sievert. The Sievert is a unit used to quantify the biological effects of ionizing radiation. Unlike the Gray, which measures the absorbed dose of radiation in any material without considering its biological impact, the Sievert takes into account the type of radiation and its impact on human health. This measurement plays a crucial role in radiation safety as it helps assess the potential health risks of exposure, allowing for appropriate safety standards and protective measures to be implemented. The Sievert is particularly important in fields such as radiology, nuclear medicine, and radiation protection, where understanding the biological implications of radiation exposure is vital to ensuring safety for both patients and healthcare workers. In contrast, terms like Roentgen, Gray, and RAD refer to other aspects of radiation measurement but do not incorporate the biological effects, which is why they are not suitable answers in this context.
