Question 1178216: As a sample of a radioactive element decays into more stable elements, the amount of radiation it gives off decreases. The level of radiation can be used to estimate how much of the original element remains. The following are some readings for a sample of radium-227:
(a)Which of these two models (quadratic or exponential) fits the data best? Justify your answer.
(b) According to each model, what amount of radium-227 will remain after 8 hours?
c) Which of these two models is superior for extrapolating beyond 6 h? Explain.
Time( h) | Radiation level (%)
0 | 100
1 | 37
2 | 15
3 | 5.0
4 | 1.8
5 | 0.7
6 | 0.3 Answer by ikleyn(53937) (Show Source):
