- Exposure to radiation Exposure to ionizing radiation may cause skin and blood damage, cataract, infertility, birth defects and cancer. The probability of radiation adverse health effects is proportional to the dose received, but no level of radiation exposure is completely safe.

Jul 7, 2023 · Every day, people inhale and ingest forms of radiation from air, food and water. Today, the most common artificial sources of human exposure to radiation are X-ray machines and radiopharmaceuticals used for diagnostic or radiotherapy and other medical devices.

- Ionizing radiation and health effects
Exposure to radiation may occur through internal or external pathways. Internal exposure to ionizing radiation occurs when a radionuclide is inhaled, ingested or otherwise enters into the bloodstream (for example, by injection or through wounds).

This page answers key questions about radiation: what is radiation, how does radiation affect people and how are we exposed to radiation? Radiation refers to the transfer of energy from one place to another. There are 2 broad categories of radiation: 1. non-ionising radiation, such as visible light, signals from mobile phones and radio waves 2. ion...
Unstable atoms in a material are said to ‘decay’ giving out ionising radiation in the process. The property of a material to decay and emit ionising radiation is called radioactivity and the material is said to be radioactive. As the unstable atoms in a radioactive material decay the atoms change to another form. The time taken for half the unstabl...
The term ‘radiation dose’ is used to describe the amount of energy absorbed by a material from ionising radiation passing through it. The most common measure of radiation dose to people is called effective dose, measured in units called sieverts. Effective dose takes account of the different sensitivities of organs in the body and the effects of di...
People have always been exposed to low levels of radiation from natural sources. On average, people in the UK receive an annual dose of 2.7 mSv. Natural sources make up approximately 84% of this dose, with the remainder coming from a variety of artificial sources.
Feb 13, 2024 · Radiation sickness is caused by being exposed to a high dose of radiation. Radiation is the energy released from atoms as either a wave or a tiny particle of matter. Radiation sickness happens when high-energy radiation damages or destroys certain cells in the body.
The radiation exposure due to cosmic rays is very dependent on altitude, and slightly on latitude: people who travel by air, thereby, increase their exposure to radiation. We are exposed to ionizing radiation from natural sources in two ways: We are surrounded by naturally-occurring radioactive elements in the soil and stones, and are bathed ...
Exposure to ionizing radiation may cause skin and blood damage, cataract, infertility, birth defects and cancer. The probability of radiation adverse health effects is proportional to the dose received, but no level of radiation exposure is completely safe.
Feb 19, 2024 · We know that radiation at high doses can cause cancer and even lead to death. How radiation is delivered affects health impact. A dose received over a period of time is less harmful than the same dose received quickly at once. Radiation exposure to one part of the body is less harmful than a dose to the whole body.
