Radiobiological effects that first appear minutes, days, or weeks after exposure are termed what?

Radiobiological effects that manifest soon after exposure, within minutes, days, or weeks, are termed short-term effects. These effects are typically a result of high doses of radiation and can include symptoms such as nausea, vomiting, fatigue, and skin irritation. They arise because of immediate biological damage caused by the radiation, affecting rapidly dividing cells such as those in the gastrointestinal tract and bone marrow.

In contrast, long-term effects generally appear months to years after exposure and may include cancer, genetic mutations, or other chronic diseases, which stem from lower doses of radiation over time. Post-latent and lag dependent are terms that do not typically classify the timing of radiobiological effects in the context of radiation exposure, and thus are not relevant in this scenario. Understanding the distinction between short-term and long-term effects is crucial in radiobiology, particularly for managing risk and making informed decisions regarding radiation safety and exposure limits.
