Homework Answers
Consider the given data
mass of the person = 66 kg
number of beta particles absorbed = 6 
105
energy of each particle = 8.74
10-14 J
Therefore, the total energy absorbed by the person can be calculated as
and the energy absorbed by the person per kg can be calculated as
Hence, grays received by the person is
Hope it helps. Please let me know if you have any questions or doubts.

Calculate the effective radiation dosage in sieverts for a 73-kg person who is exposed to 6.8 x 10' particles of alpha radiation. Only 75% of the radiation is absorbed. Assume each alpha particle has an energy of 6.9 x 10-13 J and that the RBE of the alpha particles is 15. Note that RBE is sometimes called the quality factor (Q).

Be sure to answer all parts. A 45−kg person drinks 5.0 × 102 g of milk, which has a caloric value of approximately 3.0 kJ/g. If only 17 percent of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake? Enter your answer in scientific notation. Hint: The work done in ascending is given by mgh, where m is the mass (in kg), g is the gravitational acceleration...
