Dose from a Source of Charged Particles Inside the Body

1 Dose from a Source of Charged Particles Inside the Body 

If the particle spectrum is known in multigroup form, Eq. 16.19 becomes H = DEgSgGymass (16.20) 

If the charged-particle source is localized, i.e., it can be considered a point isotropic source, the mass in the denominator of Eq. 16.20 is equal to 

Example 16.4 What is the dose rate from 1 pCi of an alpha source emitting 

This is an extremely large dose rate, the result of the energy being deposited in a very small volume.
