(a) Explanation Given Info: The half-life of phosphorus-32 is 14.3 days. The average kinetic energy of the emitted electrons is 7.00 × 10 2 KeV . The initial activity of the sample is 1.31 MBq. Formula to calculate the number of electrons emitted is, n = N 0 − N (I) N 0 is the initial number of electrons. N is the number of electrons remaining. Formula to calculate the number of electrons remaining is, N = N 0 exp [ − ( t t 1 / 2 ) ln 2 ] (II) t is the time elapsed. t 1 / 2 is the half-life. Formula to calculate the initial number of electrons is, N 0 = t 1 / 2 R 0 ln 2 (III) R 0 is the initial activity. Substitute Equations (II) and (III) in (I). n = ( t 1 / 2 R 0 ln 2 ) ( 1 − exp [ − ( t t 1 / 2 ) ln 2 ] ) Substitute 14 (b) To determine The total energy deposited. (c) To determine The absorbed dose.
