Conversion of Exposure rate constant to Air kerma rate constant

Briefly on Specific gamma ray constant and Exposure rate constant The specific gamma ray constant is the quotient of Where, is the distance from point source is the exposure rateA is the activity of the nuclide unit : R cm2 h-1 Ci-1 The exposure rate constant has been introduced later on to replace the specific…

Dose Volume Histogram 📈

Introduction Dose volume histogram was first introduced in 1979 by Goitien and Verhey. Dose Volume Histogram (DVH) are presented as structure based DVH and non- structure based DVH. Non structure based DVH are less occasionally used and predominantly structure based DVH is used, though it has gross uncertainties in the precise location of structure. DVH…

Linear Energy Transfer

The density of ionization in particle track is described by the term Linear Energy Transfer (LET). In other words, it is the measure of number of ions produced per unit path length of the track. What is difference between path length and range?The thickness of medium required for entire energy of the particle to be…
