Introduction: Alpha particle emitters are extremely destructive and detrimental to the human body, if inhaled or consumed, swallowed, or absorbed into the lungs or bloodstream. 222Rn is one of alpha-particle emitter. Material and Methods: we studying the concentrations of radon gas (222Rn) in blood samples of 10 cancer patients and 6 control measured using CR-39 detector. The samples were collected from Babylon oncology center. Results: The highest concentration of radon for cancer was 267.22 Bq/m3 , while for control was5.98 Bq/m3 . The lowest concentration of radon for patient was 16.55 Bq/m3, while for control group was 2.77 Bq/m3. Conclusion: These study concluded the level of radon concentration increased of cancer patient compare with control group, also these study concluded the level of radon in center of Babylon city higher than of rural of Babylon.

Untreated hypothyroidism can contribute to hypertension, dyslipidemia, infertility, cognitive impairment, and neuromuscular dysfunction. The management of hypothyroidism focuses on ensuring that patients receive appropriate thyroid hormone replacement therapy and monitoring their response. Hormone and supplement therapy should have beneficial effects. The present study was designed to evaluate IGF-1 and some supplements in thyroid-stimulating hormone (TSH) and thyroid hormones (T3 and T4) concentrations in response to treatment with T4, IGF-1, Zn, Se, and Vit.B12 in experimentally induced hypothyroid rats. Forth-week-old male Wistar albino rats (weight 180–250 g). Rats were given methimazole to induce hypothyroid and were randomly divided into seven groups including those treated with levothyroxine T4, IGF1, T4 + IGF1, T4 + Zinc, T4 +Selenium, T4 +B12, and T4+Zinc+ Selenium+ B12. The body weight was evaluated for each group before and after the treatment. The concentrations of TSH and thyroid hormones were measured using the ELISA technique. The data showed that the animal model of hypothyroidism had increased body weight in comparison to the control groups (P≤0.05). The body weight of rats in treatment groups with IGF-1 was significantly increased from (221 ± 16.8) g to (276.2 ± 25.9) g.
