40K is an unusual isotope, in that it decays by negative beta emission, positive beta emission, and electron capture. Find the
Q values for:
(a) negative beta emission

Expert Solution

Concept and Principle:

As per the mass-energy equivalence principle, energy and mass are interconvertible. Thus when energy is lost in chemical, nuclear, or any other energy transformation the system will also lose mass.

Q value for a reaction is the amount of energy absorbed or released during the nuclear reaction and will be equal to the energy equivalent to the lost mass.

Q value of a reaction is given by,

$Q = [m_{R} - m_{P}] c^{2}$

Here m_R is the mass of the reactant, m_P is the mass of the product, and c is the speed of flight.

11. A 60 kg person accidentally ingests a small source of alpha particles (RBE=15). The activity of the source is 0.04 Ci, the half life of the source is 110 years, and each alpha particle emitted has an energy of 0.586MEV. It takes 12 hours for the alpha source to pass through the persons digestive system and exit the body. (a) How many alpha particles are absorbed by the person (you may assume that 100% of the alpha particles emitted by the source are absorbed by the person)? (b) How much energy is deposited in the person by the source (in J)? (c) What is the absorbed dose (in rad)? (d) What is the absorbed dose (in rem)?
A 75 kg patient swallows a 33 μCi beta emitter whose half-life is 5.0 days and whose RBE is 1.6. The beta particles are emitted with an average energy of 0.35 MeV, 90% of which is absorbed by the body. You are a health care worker needing to find the patient's dose equivalent after one week. These series of steps will help you find that dose equivalent. In all questions, assume the radioactive nuclei are distributed throughout the patient's body and are not being excreted.
