How is the biological effect of radiation on living organisms primarily determined?

The biological effect of radiation on living organisms is primarily determined by both the dose and duration of exposure. The dose refers to the amount of radiation energy absorbed by the body, while the duration pertains to the length of time the organism is exposed to that radiation.

When considering biological effects, a higher dose of radiation is generally associated with a greater likelihood of adverse effects, because more energy is deposited in biological tissues, potentially causing cellular damage. Similarly, prolonged exposure, even at lower doses, can accumulate and lead to significant biological effects over time. This accumulation can impact the severity of effects such as cancer induction, tissue damage, and genetic mutations.

In conjunction, both factors must be considered in risk assessment and protective measures for individuals exposed to radiation, as they synergistically influence the level of risk and potential biological consequences. Understanding this interplay is crucial for implementing effective safety protocols and guidelines in radiation protection practices.
