|---|---|
| radiation, ionizing | Electromagnetic or corpuscular radiation capable of producing ions, directly or indirectly, in its passage through matter. The wavelengths are equal to or smaller than those of short (far) ultraviolet radiation and include gamma and X-rays and high-energy elementary particles. (12 Dec 1998) |
| radiation, nonionizing | Electromagnetic radiation which does not produce ions in matter through which it passes. Its wavelengths are generally greater than those of far ultraviolet radiation and range through the longest radio waves. (12 Dec 1998) |
| radiation-protective agents | Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. Military, purposes. (12 Dec 1998) |
| radiation-sensitizing agents | Drugs used to potentiate the effectiveness of radiation therapy in destroying unwanted cells. (12 Dec 1998) |
| synchrotron radiation | <physics> Electromagnetic energy radiated from a charged particle moving in a curved orbit (typically in a magnetic field), due to the acceleration required to change the direction of the particle's velocity. See: bremsstrahlung. Synonym: cyclotron radiation. (13 Jan 1998) |
|---|---|
| dose-response relationship, radiation | The relationship between the dose of administered radiation and the response of the organism or tissue to the radiation. (12 Dec 1998) |
| infrared radiation | Electromagnetic radiation with wavelengths between 750 nanometres and 1,000,000 nanometres (or 1 millimetre). This is more commonly known as heat energy. (09 Oct 1997) |
| internal radiation therapy | Radiation therapy in which radioactive material is placed in or near a tumour. (12 Dec 1998) |
| interstitial radiation | Radiation therapy in which a radioactive material is placed directly into a tumour. (12 Dec 1998) |
| interstitial radiation therapy | <oncology> The implantation of radioactive seeds directly into a tumour. (10 Jan 1998) |
| intraoperative radiation therapy | Treating a tumour site withradiation immediately following surgery to destroy the tumour. (09 Oct 1997) |
| ionising radiation | <radiobiology> Radiation sufficiently energetic to dislodge electrons from an atom. Ionising radiation includes x and gamma radiation, electrons (beta radiation), alpha particles (helium nuclei) and heavier charge atomic nuclei. Neutrons ionise indirectly by colliding with atomic nuclei. Alpha and gamma radiation are far more effective at producing ionisation (and therefore more likely to cause tissue or cell damage) than beta radiation or neutrons. (16 Dec 1997) |
| ionizing radiation | Corpuscular (e.g., neutrons, electrons) or electromagnetic (e.g., gamma) radiation of sufficient energy to ionise the irradiated material. (05 Mar 2000) |
| occipitothalamic radiation | The massive, fanlike fibre system passing from the lateral geniculate body of the thalamus to the visual cortex (striate or calcarine cortex, area 17 of Brodmann); the fibres follow the retrolenticular and sublenticular limbs of the internal capsule into the corona radiata but they curve back along the lateral wall of the temporal and occipital horns of the lateral ventricle to the striate cortex on the medial surface and pole of the occipital lobe. Synonym: radiatio optica, geniculocalcarine radiation, geniculocalcarine tract, Gratiolet's fibres, Gratiolet's radiation, occipitothalamic radiation, Wernicke's radiation. (05 Mar 2000) |

| electromagnetic radiation | <physics> Radiation (such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays) which consists of associated, interacting electric and magnetic field waves which travel at the speed of light. All forms of electromagnetic radiation can be transmitted through vacuum. Electromagnetic waves in plasmas are generally more complex in their behaviour, depending on their frequency. (09 Oct 1997) |
| excitation radiation | <radiobiology> Line radiation (at characteristic frequencies / wavelengths) as a result of the promotion of electrons or other constituent particles of a larger system to excited states, and the subsequent de-excitation of these states by radiative transitions. (09 Oct 1997) |
| external radiation | Radiation therapy that uses a machine located outside the body to aim high-energy rays at the cancer. (16 Dec 1997) |
| external radiation therapy | Radiation therapy using a machine located outside the body to aim high-energy rays at a tumour. (12 Dec 1998) |
