Radon is continuously emitted from natural elements, especially because of the decomposition of U-238 and Thorium-232. Radon is ordered as a second cause of lung cancer. In this paper, the absorptions of radon and thoron were stately in schools east of Baghdad, namely Abtal Al-Taf, Batalat Karbala, and In Kaldoon Schools. The concentrations of the gases are measured using the SSNTD method (solid-state nuclear track detector method). Radon gas concentrations were different and ranged from 33.8 to 63.7 Bq/m 3 , and a thoron from 48.8 to 127.1 Bq/m 3 , which are within the permissible limits stipulated in the international organization ICRP. The mean annual dose of radon and thoron gases obtained by those in the schools under study was 3.4±0.9 mSv.y -1 and the maximum value of the annual dose was 4.7 mSv.y -1 in the room of the Batalat Karbala school, while the last value was 2.6 mSv.y -1 in the garden of Ibn Kaldoon School.

Background: We can inhale, consume, or absorb the substances, causing internal irradiation. Internal and external dosages are similar everywhere. Alpha particles are heavier and more charged than ordinary ionizing radiation, which damages living tissues more. Food and air contain radioactive isotopes. Materials: The CR-39 detector technique was used to determine the alpha emissions that were present in urine samples of patients by finding their percentage. CR-39 is a simple and convenient method for the determination of alpha emission in biological samples. Results: We found the rate of alpha emission in urine samples in mBq.cm-2 to be the following: (0.063± 0.042) thyroid disorders < (0.069± 0.038)control< (0.076± 0.052) Papillary thyroid carcinoma
