Answer to Question #268908 in Python for Pere

Question

Radioactive decay of radioactive materials can be modeled by the equation

A=Aoe^t(in 2/h) , where A is the amount of the material at time t, A0 is the amount at time 0, and h is the half-life. Technetium-99 is a radioisotope that is used in imaging of the brain. It has a half-life of 6 hours. Your program should display the relative amount A/A0 in a patient body every hour for 24 hours after receiving a dose. Note: With the aid of formatting techniques documented in your note, ensure your program output matches that given below. Program Output

Answer 1

from math import e
import numpy

A0 = int(input("A0:" ))
h = 6
t = 0
i = 0
print("Hours", " Millicuries")
while t < 25:
  final = (A0 * e **(-t*(numpy.log(2)/h)))/A0
  t = t + 1
  print(i, "    ", final)
  i = i + 1
