2020年7月13日 · Low dose ionizing radiation causes solid cancer and leukemia, according to an international team of experts following a bias assessment and meta-analysis of 26 epidemiological studies. Results were reported in a JNCI monograph published July 2020.

At lower doses, ionizing radiation can cause health effects such as cardiovascular disease and cataracts, as well as cancer. It causes cancer primarily because it damages DNA, which can lead to cancer-causing gene mutations .

2023年7月27日 · Low doses of ionizing radiation can increase the risk of longer term effects such as cancer. What is ionizing radiation? Ionizing radiation is a type of energy released by atoms that travels in the form of electromagnetic waves (gamma or X …

The evidence for cancer risks provided by epidemiological studies of low-dose ionizing radiation exposure is of key relevance to radiation protection because a large fraction of the population is exposed to low doses of ionizing radiation from diagnostic medical procedures or occupationally, in addition to natural background radiation.

2024年2月19日 · Ionizing radiation is a powerful form of energy with medical applications such as diagnostic testing. At high enough doses, it can alter your body's cells and DNA. Unlike some non-ionizing radiation, it can cause serious harm or cancer with enough exposure. Radiation exists all around us and is in two forms: ionizing and non-ionizing radiation.

These studies demonstrate that exposure to moderate to high doses of radiation increases the risk of cancer in most organs. For all solid cancers combined, cancers of the thyroid, breast and lung, and leukemia, risk estimates are fairly precise, and associations have been found at relatively low doses (<0.2 Gy).

2024年7月1日 · Articles suggest a cancer prevention safety threshold of 1–20 mSv for low-dose ionizing radiation. Hematopoietic malignancies exhibit a higher incidence than solid cancers when exposed to low-dose ionizing radiation. Epigenetic regulation occurs within the low-dose range of ionizing radiation.

2020年7月1日 · Since the Biological Effects of Ionizing Radiation VII review of the epidemiological data in 2006, many subsequent publications have reported excess cancer risks from low-dose exposures. Our aim was to systematically review these studies to assess the magnitude of the risk and whether the positive findings could be explained by biases.

2023年12月17日 · Ionizing radiation is a risk factor for malignancy after prolonged exposure. Evidence from studies conducted following the Chernobyl accident, nuclear tests, environmental radiation pollution, and accidental indoor contamination reveals consistently increased chromosome aberration and micronuclei frequency in those exposed to ionizing radiation.

2020年3月20日 · The associations between radiation exposure and cancer are mostly based on populations exposed to relatively high levels of ionizing radiation (e.g., Japanese atomic bomb survivors and recipients of selected diagnostic or therapeutic medical procedures).
