What is meant by "effective dose" in radiation safety?

• A. A measure of the financial cost of radiation
• B. A measure of the biological effect of radiation, accounting for dose and type of tissue
• C. The total radiation used in a single procedure
• D. The amount of radiation a person can legally receive

Answer: (B)

The concept of "effective dose" refers to a measurement used in radiation safety to evaluate the biological effects of radiation exposure on human tissues. This measurement takes into account both the absorbed dose of radiation (the amount of energy deposited in a material by radiation) and the type of tissue that is affected. Different tissues have varying sensitivities to radiation, and the effective dose serves to quantify these differences by applying tissue weightings, allowing for a comprehensive assessment of risk across different types of exposures. By recognizing both the dose and the specific characteristics of the tissues exposed, the effective dose provides a more accurate representation of the potential health impact from radiation than merely measuring the total amount of radiation or the radiation used in a particular procedure. This measurement is crucial for making informed decisions about radiation safety practices, optimizing radiation use in medical settings, and protecting patients and healthcare providers from unnecessary radiation exposure.
