None internal conversion process with example of radioactivedecay(exrdm)

Hi,

I have a problem in my simulation of radioactive decay of radioisotope. If I use Pb-210 for primary ion, the sum energy of secondaries from initial beta decay of Pb-210 doesn't match with the Q-value(63.1keV) It seems that some x-ray after internal conversion is not produced.

I am using Geant4.8.0.p1, and the example of exrdm in radioactivedecay. Below is some output from tracking of one decay.

According to the physics reference manual, the atomic deexitation process should be followed and the internal conversion process should be properly handled.

Can anyone comment on this ?

Thank you.
