Test results indicated that Mn glass used in dosimetry could maintain sufficient color stability within dosage ranges of 3.5 x 10/sup 4/ to 10/sup 7/ r. Glass samples containing 90% MnO by weight were irradiated by a 1-kC Co/sup 60/ source at dose rates of 6.1 x 10/sup 4/, 10/sup 5/, 2.5 x 10/sup 5/, and 5.0 x 10/sup 5/ r /hr in air at 18 450 deg C in a 3 un. Concent 85% C up to dosage levels from 1.22 x 10/sup 4/ to 10/sup 7/ r. The natural fading of the induced color, and the effects of factors such as the ultraviolet, visible rays of light, heat, and d-c electric tension on the quickening of color fading were described. The induced color at 430 m was not affected either by the factors or by irradiation. (OID)
