Dosimeter - Definition

Definition


A dosimeter is an instrument used in dosimetry, its role being to indicate the quantity of ionizing radiation that a subject may have absorbed or been exposed to, either from ultraviolet rays or radioactivity. There are two types of dosimeters: the active, or operational, dosimeter, and the passive dosimeter. The first, sometimes called an electronic dosimeter, allows a direct reading, while the second permits a deferred reading. French regulation requires that every individual exposed to ionizing radiation for professional reasons must carry a dosimeter.
