Average dose rate

  1. Apr 4, 2015 #1
    A patient receives an injection of 1.11×108 Bq of 131I,30% of which goes to the thyroid, having a mass of 20 g.What is the average dose rate in the organ?

    D=1.60×10–10AE Gy s–1



    =1.60x10-10 (1.665)(0.192Mev)

    = 51μGy s–1

    This is my solution. Can anyone point out the mistake here.
