ON LATENT IMAGE FADING IN ILFORD K.0 AND K.2 EMULSIONS
Technical Report
·
OSTI ID:4726989
Fading in Ilford K.0 and K.2 emulsions was investigated at +20 and -20 un. Concent 85% C. Track segments with rates of energy loss from 0.6 to 1.8 Mev/ micron were used. K.0 and K.2 emulsions stored for 30 days at -20 un. Concent 85% C showed no evidence of fading. After a 30-day fading period, K.2 emulsion stored at +20 un. Concent 85% C and at 50% relative humidity showed less than 10% fading. K.O emulsion stored at +20 un. Concent 85% C and at 50% relative humidity showed severe fading. This is illustrated by curves of grain density vs residual range for 2-, 6-, 13-, and 30-day fading periods. (auth)
