MIRD Pamphlet No. Radionuclide Decay Schemes and Nuclear Parameters for Use in Radiation-Dose Estimation. MIRD Committee of the Society of Nuclear Medicine MIRD Pamphlet No. "S," Absorbed Dose per Unit Cumulated Activity for Selected Radionuclides and Organs. Snyder WS, Ford MS, Warner GG, et al. “S” absorbed dose per unit cumulated activity for selected radionuclides and organs. MIRD Pamphlet No. New York: Society of Nuclear Medicine; Google ScholarAuthor: Gopal B. Saha. The cumulated activity in the source organs, ã h can be calculated by the Eq. 2 [26]: where ã (t) is the activity of each organ at the time t. In this study, the accumulated source activity was calculated by plotting the non-decay-corrected time activity curves for each organ and computing the area under the curves.   (2) Values for S: "S", Absorbed Dose per Unit Cumulated Activity for Selected Radionuclides and Organs, MIRD Pamphlet No. 11 (). * Bilirubin Calculations assume that 98% of the injected activity is taken up by the liver; activity not removed in the urine in 24 hours is excreted in the intestines and no enterohepatic circulation of activity.

  Step 2: The ‘S-Factor’ S-factor is considered to be a calculation of energy emitted by radiation of certain type of isotope and fraction of that energy absorbed by organ. So, S-factor can be define as absorbed dose per unit cumulated activity.   The S-factor, S(t,s) is the mean absorbed dose to the target organ, t, from unit activity of the relevant radioisotope distributed homogeneously within the source organ, s. Note that its possible for the source and target organ to be the same entity. Cumulated activities were calculated using the same method as used for mouse dosimetry calculations. The dose calculation was done for a selected group of organs following the MIRD scheme. The S-values for Lu for adult male were extracted from RADAR website. Some special considerations were used due to the differences between the organs Cited by:   1.

For the newborn, 1-year old, and 5-year old, the “S” values calculated form the preliminary phantoms of ORNL were used.
