Final answer:
To reduce genetic radiation effects, increasing distance from the radiation source and decreasing exposure time are effective measures, with increasing distance from the source being the correct answer to the question.
Step-by-step explanation:
To reduce the likelihood of genetic radiation effects, proper radiation protection measures are crucial. One effective measure is increasing distance from the source of radiation, which significantly reduces radiation intensity, as the intensity drops inversely proportional to the square of the distance. Additionally, decreasing exposure time also reduces the likelihood of genetic damage because the amount of radiation a person is exposed to is directly related to the time they spend in a radiation environment. Therefore, the correct answer to the question is c) Increasing distance from the source.
Occupations that might lead to an increase in radiation exposure include those involving medical imaging, nuclear power plants, and certain types of research and industrial applications where radioactive materials are used.
