CONTACT RADIATION HAZARD ASSOCIATED WITH AIRCRAFT CONTAMINATION BY EARLY CLOUD PENETRATIONS,
Abstract
The contact hazard which personnel experience when working on radioactively contaminated aircraft was investigated. Measurements of the contact hazard are approximated by surveying the aircraft with a gamma survey instrument (T1B) and applying a correction factor to the readings obtained; 110 times the T1B reading (r/hr) will give the approximate contact dose (rep/hr) to the skin in areas of direct impingement of the contaminant, i.e., leading edge of the wing, nose, etc., whereas 40 times the T1B reading is applicable to the sliding surfaces, i.e., sides of the fuselage. The protection to an individual from the contact hazard realized by wearing gloves was also investigated. All gloves tested reduced the radiation intensity to the hands by at least 50% in addition to preventing the contaminant from coming in direct contact with the skin. Wearing of gloves in radiation fields of 0.1 r/hr or more is recommended. (Author)
