Chapter 19, Problem 75CWP
Interpretation Introduction

Interpretation:

Half life of Iodine- 131 is given. Number of days taken by 174g of 131I to decay to 83g of 131I is to be calculated.

Concept introduction:

  • In radioactive decay, the decomposition of a parent nuclide takes place and a new daughter nuclide is formed.
  • Decay constant is the quantity that expresses the rate of decrease of number of atoms of a radioactive element per second.
  • Half life of radioactive sample is defined as the time required for the number of nuclides to reach half of the original value.
