A new sim u la tion model for cal cu lat ing the in ter nal ex po sure of some radionuclides

A new model based on a se ries of math e mat i cal func tions for es ti mat ing ex cre tion rates fol low ing the in take of nine dif fer ent radionuclides is pre sented in this work. The radionuclides un der in ves ti ga tion are: co balt, io dine, ce sium, stron tium, ru the nium, ra dium, tho rium, plu to nium, and ura nium. The com mit ted ef fec tive dose has been cal cu lated by our model so as to ob tain the uri nary and fae cal ex cre tion rates for each radionuclide. The said model is fur ther val i dated by a com par i son with the widely spread Mondal soft ware and a sim u la tion pro gram. The re sults ob tained show a har mony be tween the Mondal pack age and the model we have con structed.
