1) In a living organism, the decay of C-14 produces 15.3 disintegrations per minute per gram of carbon. The half-life of C-14 is 5730 years. A bone sample with 2.5 g of carbon has 22.5 disintegrations per minute. How old is the bone sample in years? 2) There are three isotopes of phosphorus. Only one of them is stable. Calculate the binding energy per nucleon (in MeV) for P-30 (atomic mass = 29.9783 u). H = 1.007825 u and n...

Background (Part 1): We are continuously exposed to ionizing radiation from natural and artificial sources. All of us are exposed to radiation every day, from natural sources such as minerals in the ground and cosmic radiation to man-made sources such as medical x-rays. According to the National Council on Radiation Protection and Measurements (NCRP), the average annual radiation dose per person in the U.S. is 620 millirem. In this activity, you will use the interactive online dose calculator to estimate...

**Please Show All The Steps**
As I mentioned in the class assume that we have a GaAs (Gallium
Arsenide) sample which was doped with excessive As to produce a
resistivity of 0.05 Ωm. Owing to the presence of an unknown
acceptor impurity the actual resistivity was 0.06Ωm, the sample
remaining n-type. What were the concentrations of donors and
acceptors present?
(Please take μe=0.85 m2/Vs and assume that all impurity atoms
are ionized)
