Most employees working with radioactive materials experience chronic exposure to radiation. Chronic exposure refers to the continuous or repeated exposure to low levels of radiation over an extended period. This is often the case in settings where workers handle radioactive materials regularly, such as in laboratories, nuclear power plants, or medical facilities that utilize radioactive substances for diagnostic or therapeutic purposes.

Chronic exposure is significant because even small amounts of radiation can add up over time and potentially lead to adverse health effects. Safety protocols are established to limit this type of exposure and to monitor radiation levels to ensure they remain within acceptable limits.

In contrast, acute exposure typically involves a high level of radiation received in a short period, which is less common for most workers in environments handling radioisotopes. Intermittent exposure can occur in certain situations but is not the primary concern for routine operations in this field. Temporary exposure, while relevant in specific contexts (such as in certain medical or research applications), does not capture the ongoing nature of most employees' interactions with radioactive materials, which generally leads to a chronic exposure scenario.
