Background: The development of methods to alleviate radiation-induced health effects is important for the practical use of radiation therapy and for understanding the molecular mechanisms mediating these effects. Here, we examined the protective capability of N-acetylcysteine (NAC) on life-shortening effects induced by continuous low dose-rate gamma-ray exposure in mice. Materials and Methods: ...

The coastal area of ​​Ramsar in northern of Iran located in the province of Mazandaran has been known as the highest levels of natural radiation background in the world. The background radiation is mainly due to the presence of radioactive isotopes of the radium element and its decay products, which is brought to the surface by hot springs. In this study, the indoor gamma dose rate in Ramsar wa...

Background: There has been a growing claim that cell phone usage may have a detrimental effect on sperm chromatin. Infertile men possess anomalies in the composition of their sperm nuclei, displaying higher levels of loosely packaged chromatin and damaged DNA. In this study we examined the relationship of cell phone radiation and the protection effect of alpha_tocopherol on human sperm DNA. Mat...

Background and purpose: In recent years the use of radioactive materials for diagnostic and therapeutic purposes grew rapidly in nuclear medicine. The imaging technicians and nursing staff in radiopharmaceutical centers are in close contact with patients. Therefore, they are exposed to different radiation levels. This study was done on risk assessment of staff exposed to 99mTc-MIBI Materials...
