What type of changes does biological detection in RADIAC instruments refer to?

  1. Physical changes in the environment

  2. Changes in a living organism or system

  3. Changes in chemical properties

  4. Changes in temperature regulation

The correct answer is: Changes in a living organism or system

Biological detection in RADIAC instruments refers to changes in a living organism or system because these instruments are specifically designed to detect and measure the effects of radiation on biological materials. This can include cellular responses, organism health, or the effects of radiation exposure on flora and fauna. When RADIAC instruments assess the biological impact of radiation, they focus on how living organisms interact with radiation and how that exposure can alter biological functions or lead to various health effects. For example, detecting changes in how cells function or how organisms respond to radiation levels are vital in assessing safety and risk in environments where radiation is present.
