Only problem 8 please.
8. Consider the three component decay in Problem 7. The
half-life of the orig- inal nucleus is one day. The half-life of
the second nuclide is two days, while the third nuclide is stable.
The initial number of particles for nuclide A is 10,000, while
nuclides B and C have no initial particles. Plot the number of
particles from 0 to 10 days using ODE45 in MATLAB.

Replace each question mark with the appropriate integer or symbol. daughter nucleus: 5 BV Incorrect Iridium-192 is one radioisotope used in brachytherapy, in which a radioactive source is placed inside a patient's body to treat cancer. Brachytherapy allows the use of a higher than normal dose to be placed near the tumor while lowering the risk of damage to healthy tissue. Iridium-192 is often used in the head or...
