T HE POTENTIAL medical hazards of man's venture into space will span a number of disciplines in regard to the pathology and deranged physiology to which the human body may be subject in travel beyond the earth's atmosphere. Not the least hazard is that having to do with the effects of radiation to be encountered in free space. This problem is one which is receiving considerable attention from a...

Adverse effects and hazards which have their origin from radiation using conventional techniques like 3-D conformal radiotherapy and total radiation doses are well known. However little is known about the sprectum of especially late toxicity after radiation using new technologies like intensity modulated radiotherapy (IMRT) combined with novel target volume and dose concepts. Since IMRT allows ...

Introduction Ionising radiation is widely used in medicine, industry and education. Most people are familiar with medical applications for diagnosis and treatment of disease. However the public at large is probably not aware just how commonly it is used in industry. Such uses include: the measurement and control of various processes e.g. liquid levels in bottling and canning plants and the thic...

Exposure to radiation from different types of television sets was measured to ascertain the levels of hazards posed to the human biological system. Measurement of the annual radiation dose hazards was performed using a halogen-quenched GM tube with thin mica end window having a density of 1.5 mg/cm2, effective window diameter of 0.360 inch and side wall of 0.012 inch thick. The GM tube was plac...

BACKGROUND Radiologic diagnostic and therapeutic procedures using ionizing radiation carry potential health risks. Hence, clients' knowledge about radiation would play a key role in reducing unnecessary imaging and its impacts. However, information on client's knowledge in low income countries specifically in the Ethiopian context has been was limited. Therefore, the aim of this study was to as...

The Low Energy Booster, like any high-energy accelerator contains serious personnel hazards with the potential for deleterious results if precautions are not implemented. Hazards for most accelerators include: electrical hazards (high voltage and high current), ionizing and non-ionizing radiation, flammable gases, and high magnetic fields. For the LEB, the predominate hazards of concern are ele...
