IN THE EVENT OF A NUCLEAR WAR, KNOWLEDGE OF THE TIME OF AVAILABILITY, AFTER CONTAMINATION BY FALLOUT, FOR RE-ENTRY AND USE OF CERTAIN RESOURCES IS IMPORTANT IN PLANNING AND PREPARING FOR THE NATIONS RECOVERY. This study is limited to the estimation of the availability time for industrial complexes that are not physically damaged by the attack or by emergency shut-down, but are inaccessible because of radiological contamination by fallout. A method of calculation proposed to be suitable for all industrial complexes was applied to 5 petroleum refineries. The findings were that the dose to decontamination personnel is the primary factor limiting re-entry and use. For the standard intensity range of 100 to 30,000 rhr and dose limits of 30 r24 hr, 230 r2 wk and 1,000 ryr, the mission re-entry time for the refineries studied ranged from 1 to 35 days.
