Question

Using Table 7.4, if a person in the Ukraine at the Chernobyl plant received a dose of 1.5 x 105 millirem (mrem) of radiation at the time of the accident what would be the likely short term effect? Table 7-4.png death a drop in white blood cell count no observable effect nausea, vomiting and loss of hair Flag this Question Question 10 3 pts Suppose a nuclear fission reaction resulted in a mass difference of 0.2 g/mol (i.e. 0.2 g/mole of starting U-235 was converted to energy). Calculate the energy (in kJ) produced from one mole of fissionable U-235 using the equation E=mc2 where c=3.0 x 108 m/s [1 J = 1 kgm2/s2]. What is the exponent in the power of 10 in your answer. Less than 6 7 8 9 10 More than 10
