Dear Lior
with the AUXSCORE card one selects the particle that is depositing
the energy, not its parent. In the case of dose from induced
radioactivity, the particles depositing the energy are electrons/photons
from radioactive decay, not the radioactive nucleus itself. Therefore, if
you select Iron with the auxcard, you'll get a zero result.
When one uses the DCYSCORE card,
results are per unit time , pSv/sec
