Which unit of measure corresponds to dose equivalent in radiation?

Dose equivalent is a crucial concept in radiation protection and measurement, as it reflects the biological effect of the radiation absorbed by human tissues. The unit that corresponds to dose equivalent is the rem.

The rem (roentgen equivalent man) takes into consideration both the amount of radiation absorbed and the type of radiation's effectiveness in causing biological damage. This metric is essential in assessing the risk associated with different types of radiation exposure, as not all radiation sources affect biological tissues equally.

In addition to the rem, other units such as the rad, gray, and sievert are also used in the context of radiation measurement. However, the gray simply measures absorbed dose (energy deposited per unit mass of tissue) without factoring in its biological impact. The sievert is another unit for dose equivalent used internationally and is directly related to the rem (1 rem equals 0.01 sieverts).

Thus, while rem is historically significant in the United States for conveying dose equivalent, the direct answer to the question concerning which unit specifically represents dose equivalent is indeed the rem.
