| highly repetitive DNA | <molecular biology> The fraction of the eukaryotic genome which consists of a short sequence of nucleotides that is repeated thousands of times all over the genome. Highly repetitive DNA is very similar to satellite DNA. (09 Oct 1997) |

| ignition | <radiobiology> In fusion, as in an ordinary (chemical) fire, ignition is the point where the temperature and confinement of heat in the fuel (plasma in the case of fusion) are such that energy released from ongoing reactions is sufficient to maintain the temperature of the system, and no external heating is needed. An ignited fusion plasma produces so much energy from fusion reactions that the plasma is fully heated by fusion reaction products (alpha particles in the case of D-T fusion), and the plasma no longer needs any external source of power to maintain its temperature. (The plasma may, however, still need something to maintain its confinement, this gives us control over the fusion reaction and helps prevent fusion reactors from having meltdown problems like fission reactors.) (09 Oct 1997) |
| ignition temperature | <radiobiology> For given values of density and energy confinement, the temperature at which ignition occurs. (see ignition above) (09 Oct 1997) |
| flammable | The property of burning readily and quickly. Synonym: inflammable. Origin: L. Flamma, flame (05 Mar 2000) |
| flammable anaesthetic | An inhalation anaesthetic that supports combustion and forms explosive mixtures with oxidizing gases. (05 Mar 2000) |
| maternal exposure | Exposure of the female parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. It includes pre-conception maternal exposure. (12 Dec 1998) |
| maximum permissible exposure level | The highest level of exposure to a substance, usually noxious, in the environment or during diagnostic and therapeutic procedures, that a body can tolerate without injury. (12 Dec 1998) |
| paternal exposure | Exposure of the male parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. (12 Dec 1998) |
| permissible exposure limit | An occupational health standard to safeguard workers against dangerous contaminants in the workplace. (05 Mar 2000) |
| prenatal exposure delayed effects | Delayed effects on offspring of maternal or foetal prenatal exposure to drugs, radiation and other physical agents, manipulation, nutrition, stress, etc. (12 Dec 1998) |
| short-term exposure limit | The maximum concentration of a chemical to which workers may be exposed continuously for up to 15 minutes without danger to health or work efficiency and safety. (05 Mar 2000) |
| dental pulp exposure | The result of pathological changes in the hard tissue of a tooth caused by carious lesions, mechanical factors, or trauma, which render the pulp susceptible to bacterial invasion from the external environment. (12 Dec 1998) |
| inhalation exposure | The exposure to potentially harmful chemical, physical, or biological agents by inhaling them. (12 Dec 1998) |
| occupational exposure | The exposure to potentially harmful chemical, physical, or biological agents that occurs as a result of one's occupation. (12 Dec 1998) |
| environmental exposure | The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals. (12 Dec 1998) |
