The environmental monitoring of radon in the female blood and urine with the cancer problems has been carried out by using RAD7. This study has been undertaken for the purpose of health risk assessments. The significant of the results is this study indicate to the health risk assessments by showing association between radon concentration of blood and urine and cancers. The concentration of radon in blood samples varies from 417 to 714 Bq m À3 with an average of 570.25 Bq m À3 before irradiation and varies from 463 to 881 Bq m À3 with an average of 734.50 after irradiation. The concentration of radon in urine samples varies from 149 to 289 Bq m À3 with an average of 208.50 Bq m À3 before irradiation and varies from 239 to 1990 Bq m À3 with an average of 1062.62 Bq m À3 after irradiation. This study shows association between radon and cancers, also the results showed that the Rad7 particularly, has ability to measuring the concentration of blood and urine samples with higher levels of radon and correlation together.

Introduction: Radon is a radioactive gas released from the normaldecay of uranium in rocks and soil depending on local geology. Radioactive decay of uranium through radium produces radon. Materials and Methods: In the present work, seventeen plant (vegetables) samples collected from Sulaimania Governorate. The plants have been analyzed and examined to measure the level of radon (222Rn) and thoron (220Rn) using plastic track detector (CR-39) for evaluation of radon and thoron concentration in this region. Results and Discussion: The results indicated that the higher andlower radon concentration have been found in Halabjay-con, and inSulaimani-center, to be (119.72 Bq.m-3, 3.236 pCi/L), (54.36 Bq.m-3,1.469 pCi/L), respectively, and the higher and lower thoron concentration have been found in Qaladza and in Sulaimani-center, to be (733.66 Bq.m-3, 19.828 pCi/L), (227.33 Bq.m-3, 9.117 pCi/L), respectively. Radiation level compared with the standard level known by the EPA (4 pCi/L) and190 Bqm-3. The concentration of radon in all sample plants is less than international standard level 4(pCi/L)and190 (Bqm-3), therefore the human in safety. The average effective dose equivalent (EDE) of radon from plants determined was (7.2) μSv.y-1 for all the samples. This is lower than the normal value of (1.3) mSv.y-1 given by EPA. Conclusions: This study showed that the contamination in the plant (vegetables) is normal and is not considered a great radial dose for plants and consequently for humans.
