Radiation effects that are limited to the exposed population are referred to as what?

The correct answer is somatic effects. Somatic effects of radiation damage are those that occur in individuals who are directly exposed to the radiation. These effects manifest in the body of the exposed person and can result in various health issues, such as skin burns, radiation sickness, or an increased risk of cancer, depending on the dose and duration of exposure.

In contrast, genetic effects result from radiation exposure that impacts the germ cells, potentially causing harm that is passed on to future generations, rather than affecting the individual who was exposed directly.

Acute effects refer to immediate health impacts following a high dose of radiation exposure, while chronic effects are long-term consequences that develop over time, which may not be exclusive to the initially exposed individual and can also influence those who were not directly exposed. Thus, focusing on the nature of the effects, somatic effects specifically denote changes that occur within the exposed population.
