| PSAP | primary public safety answering point; prosaposin; pulmonary surfactant apoprotein |
| PTSM | Plant, Technology and Safety Management |
| RADS | reactive airways dysfunction syndrome; retrospective assessment of drug safety |
| RSO | radiation safety officer; Resident Surgical Officer; right superior oblique [muscle] |
| relative biological effectiveness | The ratio of radiation dosages required to produce identical change based on a formula comparing other types of radiation with that of gamma or roentgen rays. (12 Dec 1998) |
|---|---|
| pest control, biological | The use of biological mechanisms, usually involving living organisms such as bacteria, for the reduction or regulation of the population of noxious, destructive, or dangerous pests. Environmental concerns have focused attention on natural forms of disease control as potentially safe and effective alternatives to chemical pesticides. This has led to increased efforts to develop control strategies that rely on natural predators and parasites or that involve genetically engineered microbial pest control agents. (12 Dec 1998) |
| models, biological | Theoretical representations that simulate the behaviour or activity of biological processes or diseases. For disease models in living animals, disease models, animal is available. Biological models include the use of mathematical equations, computers, and other electronic equipment. (12 Dec 1998) |
| immunologic and biological factors | A collective grouping for biologically active substances that play a role in the functioning of the immune system and those that show biological or physiological activity. (12 Dec 1998) |
| integrated biological hazard potential | <radiobiology> Total biological hazard potential of a collection of radioactive materials summed over their decay lifetimes. One measure of the integrated biological hazard potential is the amount of water one would need to use to dilute the materials to the point where the water would be safe to drink. (09 Oct 1997) |
