a. Whole body badge:

The whole body badge is used to determine an individuals whole body deep and skin dose. It should be worn on the torso of the body (e.g., on a belt loop or on a lab coat chest pocket).

b. Ring badge:

Individuals who are issued whole body badges and handle radioactive material are also required to wear a ring badge. These badges are available in small, medium, or large to accommodate different finger sizes. Medium rings will be ordered unless another specification is made. Ring badges should be worn on one of the fingers of the dominant hand (i.e., the hand one uses the most). For the most accurate measurement, the wide part of the ring, which contains the participant information, should be positioned toward the palm side of the hand. When using radioactive material, ring badges should be worn under protective gloves to prevent contamination.
