Modern medicine cannot exist without diagnostic and therapeutic methods that are based on ionizing radiation. Therefore it is necessary to understand interactions between this form of energy living matter make a full use progress in radiobiology. Ionizing radiation widely used for relatively long time, how known, disproportionately huge doses particularly harmful organisms including humans. How...

Introduction: Nowadays, X-ray radiographic imaging plays an essential role in disease diagnosis and treatment. In addition to benefits, X-rays have harmful effects for both patients and radiographers. Observing radiation protection principles reduces radiation exposure and the probability of radiation risk. Therefore, we sought to assess the knowledge, attitude, and performance of radiographers...

The harmful effects of ultraviolet radiation on aquatic animals, due to ozone layer reduction, have been long studied in recent years. Exposure of Rainbow Trout larvae (Oncorhynchus mykiss) to Ultraviolet-B radiation (UV-B) at different doses (68.75 µw/cm2 and 94.83 µw/cm2 as the minimum and maximum dose of UV-B in natural environment respectively) for 15 minutes once a day in dark condition in...

background: in many studies, chemicals and natural materials were tested to reduce the harmful effects of radiation. it is known that famotidine and vitamin c reduce dna damage. objective: the aim of this study was to evaluate the radioprotective effect of vitamin c, cimetidine and famotidine on gamma-radiation-induced damage on mouse bone marrow.  methods: six-to-seven week male nmri mice (28 ...

There are several animal experiments showing that high doses of ionizing radiation lead to strongly enhanced leakage of taurine from damaged cells into the extracellular fluid, followed by enhanced urinary excretion. This radiation-induced taurine depletion can itself have various harmful effects (as will also be the case when taurine depletion is due to other causes, such as alcohol abuse or c...

Introduction: (259 words) Sunscreen is essential in preventing skin damage caused by harmful ultraviolet radiation. Regular and appropriate sunscreen application delays photoaging reduces cancer risk. This study aims to assess the general knowledge practice of among medical undergraduates Nepal.

Radiation exposure through environmental, medical, and occupational settings is increasingly common. While radiation has harmful effects, it has utility in many applications such as radiotherapy for cancer. To increase the efficacy of radiation treatment and minimize its risks, a better understanding of the individual differences in radiosensitivity and the molecular basis of radiation response...

Introduction: Ionizing radiation is non-surgical treatment of brain tumors and metastases. Preclinical studies have showed main insights into harmful effects of radiation on the nervous system in vivo and in vitro. Cognitive impairment such as progressive memory, executive and attention performance deficits indicates a significant risk for patients experiencing conventional rad...
