What potential risk arises from repeated exposure to certain radioactive isotopes in the body?

Increased immunity
Harmful accumulation of isotopes
Permanent immunity to radiation
No significant risk

The correct answer is: Harmful accumulation of isotopes

Repeated exposure to certain radioactive isotopes in the body can lead to harmful accumulation of isotopes, which poses serious health risks. Radioactive isotopes emit radiation as they decay, and if these isotopes are ingested or enter the body through other means, they can begin to accumulate in tissues and organs. Over time, this accumulation can increase the dose of radiation the tissues are exposed to, which can result in cellular damage, increased risk of cancer, and other adverse health effects. The body's ability to eliminate radioactive materials is limited, and certain isotopes can persist in the body and continue to contribute to radiation exposure for extended periods. This prolonged exposure can enhance the likelihood of negative biological effects, making it crucial to minimize exposure and manage the presence of such isotopes in any occupational or environmental setting involving radiation safety.
