When to Wear Extremity TLDs

1. whenever you handle unshielded beta sources ;
2. when working with the whole body shielded except for the hands;
3. when handling small non-shielded gamma sources ;
4. for decontamination jobs when beta contamination  is present;
5. for glove box operations;
6. for I source operations;
7. in any radiation field which would give the extremities or more;

Great care should be taken when choosing where to wear the TLD especially when working with beta sources or close to point sources. Extremity TLD readings below are not recorded as they are not accurate below this level.
