What does the term 'short term exposure' refer to in radiation?

The term 'short term exposure' in radiation refers specifically to acute exposure that occurs over a brief period. This type of exposure is typically characterized by high levels of radiation absorbed in a short duration, which can result in immediate effects on biological systems. For instance, short term radiation exposure may happen during a diagnostic imaging procedure or an accidental release of radiation where individuals are exposed for a short time. Understanding this concept is crucial in fields like radiology and radiation safety, as it helps differentiate between acute and chronic effects of radiation on human health.

Chronic exposure, in contrast, refers to prolonged or repeated exposure over time, often leading to cumulative health effects. Long-lasting effects stem from such chronic exposures rather than from short-term incidents. Continuous exposure over a prolonged period can also result in different health outcomes, further emphasizing the importance of distinguishing between the two types of exposure.
