In order to detect SARS, airport officials would use infrared cameras to find potential carriers. A healthy individual would be detected to emit 100microwatts at 37C body temperature, what would a sick individual at 40C body temperature emit? With this answer, what is the difference in emission of a sick individual and a healthy one? 2. Relevant equations Radiation out = (5.67*10^-8)(e)(A)(T)^4 Where e ~ 1. 3. The attempt at a solution 0.0001W = (5.67*10^-8)(1)(A)(37)^4 A = 0.000941044249m^2 X W = (5.67*10^-8)(1)(0.000941044249)(40)^4 X W = 0.000136594455 0.000136594455-0.0001 = 0.00003659W = 36.59 microwatts However, this is apparently the wrong answer. Am I going at the problem in a completely wrong direction? Thanks alot for any help.
