Which unit is commonly used to quantify radiation exposure for deterministic effects?

The unit commonly used to quantify radiation exposure for deterministic effects is the Gray (Gy). Deterministic effects, also known as non-stochastic effects, occur when a certain threshold level of radiation exposure is exceeded. These effects are directly related to the amount of absorbed dose and can result in immediate or short-term health consequences, such as skin burns or radiation syndrome.

The Gray is defined as the absorption of one joule of radiation energy by one kilogram of matter. This quantitative measure provides a direct link between the radiation dose received and the potential biological effects, making it particularly useful in assessing deterministic effects.

Other options like millimeters, liters, and amperes measure entirely different concepts and are not used in the context of specifying radiation exposure. Millimeters are a unit of length, liters measure volume, and amperes are a unit of electric current. Therefore, these units do not apply to radiation exposure assessment.
