an accident wherein particles, surfaces are contaminated with hot it is necessary to have a standard to arnly *o decontamination measures. The number of particles that can be resuspended from surfaces has been the subject of a number of experiments. These experiments have usually resulted in the determination of a resuspension factor RF R. (m72) m L. values. 23 = (RF). The RF is defined by: concentration in air (uCi/m?) ; = = Concentration on surface (uCi/m¢) Kathren has reviewed the data cbtained on RF He indicates and its compounds that, "reported [RF] values for plutonium range over 11 orders of magnitude." This 11 orders corresponds to values between 1071 to 107ll ml. Kathren indicates that, "an RF of 1074 ml, conservative is appropriate." %4 although Langham indicates that a member of the Danish scientific team used an RF=1073 m1 during the Thule deliberation. ®> 83/ Kathren, R.L., We would recommend that "Towards interim acceptable surface con- tamination levels for environmental Pu02," BNWL-SA-1510, Battelle Northwest Laboratory, Richland, Washington, April 1968, pp. 3-4. 84/ Ibid, p. 4. 85/ Langham, Wright H., Op. cit., p. 5. The Thule Deliberations refer to the deliberations following the accidental crash of a B-52 bomber carrying nuclear weapons near Thule Air Force Base in Greenland. The high explosives in the weapons detonated and dispersed the plutonium. ote me aereer = weeIeee “ea! ™ oa’ . be, ‘ .a Ma Sake ont Lote fy a i we yey gee JOM Se - . wie wey uy.
