| radio | 1. <physics> The transmission and reception of electric impulses or signals by means of electric waves without a connecting wire, or the use of these waves for the wireless transmission of electric impulses into which sound is converted. 2. <anatomy, prefix> A combining form indicating connection with, or relation to, a radius or ray; specifically, with the radius of the forearm; as, radio-ulnar, radiomuscular, radiocarpal. Origin: L. Radius, ray (21 Jun 2000) |

| radio-flagellata | <zoology> A group of Protozoa having both flagella and pseudopodia. Origin: NL. See Radiate, and Flagellata. Source: Websters Dictionary (01 Mar 1998) |
| radio frequency current drive | <radiobiology> Plasma waves in the radio-frequency range can be used to push plasma particles in such a way that current forms in the plasma, this is a method of non-inductive current drive which would allow for steady-state fusion reactors to operate. (09 Oct 1997) |
| radio frequency heating | <radiobiology> Process for heating the plasma by transferring energy to ions or electrons using waves generated by an external oscillator at an appropriate frequency. (This is similar to how a microwave oven heats food.) There are various types: See: ECRH, ICRH, and Lower Hybrid. (09 Oct 1997) |
| radio frequency or radiofrequency | <physics> Term used to describe electromagnetic radiation with frequencies less than infrared, but greater than audio frequencies, i.e., greater than about 15,000 Hz. Wavelengths are therefore less than about 20,000 km and greater than about 0.01 mm. (These numbers are not precise.) (09 Oct 1997) |
| radio label | A mildly radioactive molecule that is used to tag another molecule (such as a protein) so that it can be identified as it goes through some kind of biochemical process. (09 Oct 1997) |
| radio wave | <physics> Electromagnetic radiation with wavelengths of 300 millimetres or longer (even up to several kilometres). Radiation of this type is used to broadcast radio and television signals, and has frequencies up to thousands of megahertz (or one gigahertz). (09 Oct 1997) |
| radio waves | That portion of the electromagnetic spectrum beyond the microwaves, with wavelengths as high as 30 km. They are used in communications, including television. Short wave or hf (high frequency), uhf (ultrahigh frequency) and vhf (very high frequency) waves are used in citisen's band communication. (12 Dec 1998) |
| serum albumin, radio-iodinated | <chemical> Normal human serum albumin mildly iodinated with radioactive iodine (131-I) which has a half-life of 8 days, and emits beta and gamma rays. It is used as a diagnostic aid in blood volume determination. Pharmacological action: radiopharmaceuticals. (12 Dec 1998) |
| amputation knife | A broad-bladed knife used primarily for transecting large muscles during major amputations. (05 Mar 2000) |
| Beer's knife | A triangular knife with a sharp point and one sharp edge, formerly used for incision for cataract. (05 Mar 2000) |
| valvotomy knife | A knife used in mitral or venous valvular surgery; also called valvulotome. (05 Mar 2000) |
| gamma knife | <radiobiology> A special multi-source irradiation machine which focus a high intesity of irradiation on a small area: it is used as local therapy in especially brain tumours. This is investigational and is not part of the routine array of cancer treatments. (16 Dec 1997) |
| gamma ray knife | A beam of high energy X-rays. See: radiosurgery. (05 Mar 2000) |
| cartilage knife | A very stiff scalpel-shaped knife used in cutting cartilage. Synonym: cartilage knife, ecchondrotome. Origin: chondro-+ G. Tome, cutting (05 Mar 2000) |
