How big is the risk from medical imaging to future generations?

We know that very high radiation doses can hurt or kill eggs and sperm. However, diagnostic radiology (eg X-ray or CT) uses only low radiation dose. These doses are much less than the doses that can have devastating effects on ova and sperm. The potential impact of exposed parents on human descendants has been studied, but no impact has been detected. Therefore, diagnostic radiation, including exposure of reproductive organs to low levels of radiation, is considered safe from the perspective of genetic influence.

Exposure to sperm or ova is usually negligible if the testes or ovaries are not directly exposed. Even if germ cells are directly exposed, the dose of the diagnostic test is inherently not dangerous. No studies have shown that exposure to low levels of radiation from eggs and sperm may lead to congenital defects or miscarriages. Therefore, the risk is very small (substantially zero). In other words, this risk is less than 3% of all opportunities for birth defects in all fetuses due to radiation independent factors. Even in cancer patients receiving relatively high levels of radiation and ovarian exposure to chemotherapy, long-term radiation effects have not been demonstrated. In fact, cancer patients temporarily become infertile after being exposed to high doses of radiation after exposure to the reproductive tract after chemotherapy, then recover and then have healthy children.

Individual risk associated with radiation exposure of medical images is generally low, its benefits are important, but a number of exposed individuals are a public health problem. Reasons and optimization are the two basic principles of radiation protection in medical exposure, and the four are as follows. Medical exposures should be justified by comparing the anticipated diagnostic or therapeutic benefits with potential radiation impairments, taking into account the benefits and risks of medical exposure. Alternative techniques that do not include radiation are available. The procedure should be judged to be more advantageous than damage.

There is a danger that the patient is exposed to medical imaging radiation. Because ionizing radiation can damage DNA, exposure can increase the risk of cancer in your lifetime. Individual tests may not be so dangerous, but millions of tests are done each year, and radiation exposure of medical images is an important public health issue 10. It is estimated that about 29,000 future cancers may be involved in the CT scan performed in the United States in 2007. 11 Smith-Bindman et al.

Like all medical procedures, computed tomography (CT), fluoroscopy, and nuclear medicine imaging have advantages and risks. These types of imaging procedures have resulted in improvements in the diagnosis and treatment of many medical conditions. At the same time, these types of examination subject the patient to ionizing radiation (hereinafter referred to as "radiation"), which can increase the risk of cancer in its lifetime.
