Medical diagnostic X-ray workers are one occupational group that expose to the long-term low-dose external radiation over their working lifetime, and they may under risk of different cancers. This study aims to determine the relationship between the occupational X-ray radiation exposure and cancer risk among these workers in Jiangsu, China. We conducted Nested case-control study to investigate ...
background: radiation therapy uses high-energy radiation to kill cancer cells. photoneutron contamination and induced radioactivity of high energy therapeutic photon beams are considered as the main source of occupational exposure to radiation therapists who works with linear accelerators operating above 10 mv. materials and methods: the gamma dose rates were measured after termination of diff...
Sun-exposure is one of the risk factors associated with the development of a cutaneous neoplasm. In melanoma, the Ras-Raf-MEK-ERK (MAPK) signaling pathway is constitutively activated through multiple mechanisms, including B-Raf mutation. It has been hypothesized that B-Raf mutations in melanocytic lesions arise from DNA damage induced by ultraviolet (UV) radiation. However, it is still discusse...
dear editor: the nuclear denotation due to the leakage from nuclear electricity plant in japan after the giant tsunami is a great concern. there are many possible health effects including induction of ophthalmic disorder on the affected population to the nuclear denotation. indeed the observation on the effect of radioactive leaking from the nuclear plant after the well-known nuclear leakage ...
