Which of the following describes safe levels of radiation exposure?

• A. Levels that cause noticeable genetic changes
• B. Levels that do not change the genetic makeup of a cell
• C. Levels that can safely be ignored
• D. Levels that cause temporary damage

Answer: (B)

The correct answer identifies safe levels of radiation exposure as those that do not change the genetic makeup of a cell. This definition aligns with the fundamental principles of radiation safety, which emphasize minimizing exposure to ionizing radiation to prevent any alterations in cellular DNA or genetic material. When radiation does not induce changes to the genetic makeup, it reflects a threshold where the risk of harmful biological effects is effectively managed. In the realm of radiation safety, any level of exposure that leads to genetic changes is considered unsafe, as such changes can potentially lead to mutations and subsequent long-term health issues, including cancer. Thus, avoiding genetic alterations is a crucial criterion for determining safety in exposure levels. The other options imply varying degrees of risk or effects tied to radiation exposure that deviate from safe levels. Types of radiation exposure that result in noticeable genetic changes, temporary damage, or can be considered negligible do not support the idea of safety in terms of biological impact, making them inappropriate definitions of what constitutes safe radiation exposure.
