Interactive RadioEpidemiological Program - Probability of Cancer Causation from Radiation

Estimate of Absorbed Organ Dose (cGy)

Absorbed Organ Dose (cGy) = Equivalent Organ Dose (cSv) - input by the user Reference radiation weighting factor (w_r)

The absorbed organ dose (cGy) is calculated by dividing the input equivalent organ dose (input by the user) by the specified reference radiation weighting factor value of w_r.

The reference values of w_r are as follows:

Radiation Type Reference w_r
electrons E<15 keV
1
electrons E>15 keV
1
photons E<30 keV
1
photons E=30-250 keV
1
photons E>250 keV
1
neutrons E<10 keV
5
neutrons E=10-100 keV
10
neutrons E=100keV - 2MeV
20
neutrons E=2-20 MeV
10
neutrons E>20 Mev
