Interpretation Introduction

Interpretation: The time required to take for the radioactivity due to radon to fall to a level considered acceptable by the EPA if the starting activity is 2.25×103dps/L should be determined.

Concept Introduction:

  • An unstable nucleus emits radiation spontaneously to become stable nuclei by losing energy. This process of emission of radiation by unstable nuclei is known as radioactive decay.
  • Radioactive decay is in the first order kinetics. Rate of radioactive decay at a time t is,
  • Rate of decay at a time R = k Nk-Firstorderrateconstant and its unit is t1N-numberofradioactivenucleipresentattime't

    Suppose the number of radioactive nuclei at time zero is N0 and at a time t is Nt ,

                                     lnNtN0=-kt

  • Half-life of radioactive decay is the time required for a radioactive sample to decay to one half of the atomic nucleus.

                    Half-life of the radiation,  t1/2=0.693k

  • The level considered acceptable by EPA is 4 picocuries.

1picocurie=3.70×10-2disintegrationpersec

To determine: Rate constant k for the given reaction.
