Annual Committed Effective Dose from Various Phytotherapeutic Preparations (due to <sup>238</sup>U, <sup>232</sup>Th, <sup>222</sup>Rn and <sup>220</sup>Rn) Estimated for Adult Moroccan Patients

We use a nuclear technique based on the determination of detection efficiencies solid state track detectors CR-39 and LR-115 type II (SSNTDs) for alpha particles emitted from series uranium-238 thorium-232 in phytotherapeutic sample measurement densities registered these to assess activities due uranium-238; thorium-232; radon thoron samples preparations consumed by Moroccan adult patients. For modern preparations, 238U, 232Th 222Rn range 14.27 mBq/kg 22.02 mBq/kg, 6.27 9.64 Bq/kg respectively. classical 16.73 24 7.34 10.82 24.72 A dosimetric model ingestion has been highlighted determine committed equivalent dose different compartments human gastrointestinal system The maximum overall effective 232Th, after studied was found equal 38 × 10-8 S·vy-1 which is less than limit given international commission radiological protection it publication 56.
