--15- dogs and each will have its own control of @ small nort which admits all of the thermel radiant energy. The only Studies which will be made on the burned areas are 1) descrintion of intact lesions, sup -lemented by Kodachrome ohotography, and 2?) histological examination of bionsy snecimens. Another iological test that has just been included at the reauest of the surgeon General's Cf°ice is the effect of thernmrl redistions on wall nieces of material in contact with the ~kin. Twelve such tests will be made on four animels in the outer station-. (This will be integrated with the materiel testing progrem being car ied out by the N.D.R.U.) Each station will have an integrating celorimeter which will measure the total radiant energy. These instruments have been designed so that their records of total energy can be broken down in terms of N.R.L. data into time and spectral distribution. The stations are nleced so that a large range of energy is covered, It is estimated thet the minimel energy studied during the firet test will be 3.3 to 3.3 calories per Sa. while the meximum will be 57 to 125 cal/em’. cm. A comparable energy range will be studied during the second test. The nNinimal energies are ap -roximately those reauired to produce threshold effects (5.7 cal/sa. cm/sec. ). These estimates of thermal energies are cuite uncertain. They depend uvon who makes the celculation and will certcinly vary with bomb efficiency, atmospheric conditions, etc.. These studies have been well controlled by vrelixzinary experimentction here at Rochester. 131 individual tests on DO® ARCHIVES
