Radiological assessment of cartridge 120-mm, APFSDS-T, XM829 ammunition

The components of the XM829 round effectively shield out nonpenetrating beta radiation emitted by the depleted uranium; however, photons cna penetrate the components of the round and are therefore the predominant emission. The radiation levels associated with the XM829 ammunition are low. The maximum emissions measured from a cartridge are not likely to result in exposure to military personnel above the maximum permissible nonoccupational dose limits listed in Army Regulation (AR) 40-14. Based upon the specifications contained in 49 CFR 173.424 and the radiation measurement data, the XM829 shipping package may be excepted from the specification packaging, marking and labeling requirements of subpart 49 CFR 173 as long as the outer surface of the uranium is enclosed in an inactive sheath and the conditions specified in 49 CFR 421 (b), (c), and (d) are met.
