There was no history of maternal illness, exposure to radiation, drug intake during pregnancy or consanguinity between parents.
Hormone replacement therapy (HRT) for menopause, ionising radiation, alcohol intake, night shift work and some specific genetic mutations are also established risk factors [ 4- 9].
In comparison, the RBM dose due to natural sources of exposure (including radon, terrestrial and cosmic gamma radiation, and intake of natural radionuclides) (Billon et al, 2005; Evrard et al, 2005, 2006) has been estimated to be 2700 μSv y−1 for children, and the dose due to medical examinations has been estimated to be approximately 740 μSv y−1 (Rommens et al, 2001).
The main objective of this paper is to identify the mechanism of generation, propagation and radiation of the intake noise.
In healthy people the most important sources of the vitamin D are the cutaneous production of vitamin D stimulated by solar radiation and dietary intake.
Other factors which can be more readily influenced include previous intraocular inflammation, chronic systemic steroid use, diabetes, under-nutrition (possibly due to a lack of antioxidants), and perhaps UV radiation, high alcohol intake, and smoking (West and Valmadrid 1995).
I live close to a power plant but I don't think I'm getting my daily intake of radiation exposure.
There are numerous risk factors for PTC, including radiation exposure, insufficient iodine intake, hormonal factors, and family history [ 2].
This impacts the estimation of intake and radiation dose, especially the bone dose, when aiming for personalized occupational monitoring data.
Adequate levels of 25(OH D, the storage form of vitamin D, are dependent on cutaneous synthesis stimulated by ultraviolet radiation and/or adequate dietary intake of fortified foods and nutritional supplements.
