The assertion that exposure to ionizing radiation is limited solely to X-rays and CT scans is inaccurate. This is why the answer is false. Ionizing radiation can come from various sources, not just medical imaging. Natural background radiation, such as cosmic rays from space, radon gas from the ground, and some types of radiation from the earth itself, contribute to a person’s cumulative exposure.

Additionally, certain occupations and industrial processes can also expose individuals to ionizing radiation, such as work in nuclear power plants, radiographic testing, and even some types of smoke detectors. Therefore, it's essential to recognize that everyday life can involve exposure to ionizing radiation beyond medical procedures, making it incorrect to assert that we are only exposed during these specific instances.
