A beta emitter with decay rate of (4.30 + A) x 109 Bq is inserted into a tumor for a total time of (5.80 + B) minutes. If the beta particles have an average energy of (235 + C) keV, determine the total energy released in joules (J).. Give your answer with three significant figures.
A = 5
B = 8
C = 85

(c) The isotope phosphorous-32 (32P) is a beta (8-) radioactive decay emitter with a hall- life of 14.5 days. (v) Calculate the energy in units of MeV for the energy released in the decay of one 32 15 P nucleus. (vi) Determine the total energy, in units of MeV, that has been released by the sample in this 3-day period of time.

2. Consider the beta decay of tritium (eq 2). H → He + je As you did in Question 1 for the neutron decay of H-2, determine the following for the beta decay of H-3: (a) the rest mass of the reactant (in kg, with six significant figures); (b) the sum of rest masses of the products (in kg, with six significant figures); (c) the mass defect; and (d) the nuclear binding energy of tritium (in...

A 95 kg patient swallows a 34 ?Ci 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...

Technetium Dosage. Radioactive isotopes are often used for medical imaging. Technetium-99m (Tc-99m) is a particularly popular isotope since it has a short half-life and is easy to make. Also, Tc-99m can be chemically bonded to a number of different compounds and cell types for imaging different parts of the body. Tc-99m has a half-life of 6.02 hours. It decays into Tc-99 by emitting a gamma ray of energy 140 keV. For this problem, assume that Tc-99m is present in the...
