i “ ~-15- dogs and each will have its own control of a small vort which admits all of the thermel radiant energy. The only studies which will be made on the burned areas are 1) description of intact lesions, sun:lemented by Kodachrome photography, end 2?) histological exeminetion of biopsy specimens. Another biological test that has just been included at the recuest of the Surgeon General's Cf"ice is the effect of therme 1 redistions on small rieces of material in contact with the skin. Twelve such tests will be made on four animals in the outer stations. (This will be integrated with the naterial testing rrogrem being car ied out by the N.0.2.1.) Sach station will have ean integreting calorimeter which will measure the total radiant energy. These instruments have been desizned so that their records of total energy can be broken dovn in terns of N.R.G. data into tine and spectral distribution. The stations are nleced so thet 2a lerge renge of energy is covered. It is estimeted thet the ninimel energy studied during the first test will be 3.3 to 3.3 calories per sa. while the meyimun will be 57 to 125 cal/em>. cm. A comparable energy range «111 be studied during the second test. The mininal energies are ap-roxinetely those recuired to produce threshold effects (5.7 cal/sa. cm/sec.). These estimates of thernal energies are cuite uncertain. hey denend ton who mekes the cclculation end will certeinly vary with bonb efTiciency, atnosvheric conditions, etc.. These studies have been well controlled by prelintinery experinentzation here at Rochester. 131 individual tests on JS D9 ASmHryrs GG
