"M" indicates that each of the beta-ganuna or neutron dosimeters during the reporting period was less than the vendor's minimum measurable quantity of 10 mrem for x-and gamma rays.
and thermal reutrons, 40 mrem for energetic betas, 20 mrcm for fast neutrons. "N/A" indicates that there was no extremity monitoring conducted or required for the group.
(2) DDE applies to external whole-body exposure and is the dose eq tivalent at a tissue depth of I 2
cm(1000 mg/cm ),
(3) SDE applies to skin or extremity external exposure, and is the dose equivalent at a tissue 2
2 depth of 0.007 cm (7 mg/cm ) averaged over an area of I cm,
"(4) LDE applies to the external exposure of tic eye lens and is taken as the dose equivalent at a 2
tissue depth of 0.3 cm (300 mg/cm ).
i (5) Pocket ionization chambers (PICS) are issued to persons who enter radioactive l
materials /restncted areas for periods of short duration, i.e., a few hours or days annually. A l-total of 273 issuance cards were filled out, and none recorded a postive dose value.
(6) Exposure calculated from tritium bioassay. The tritium source was state license material for a t
neutron genemtor.
