In some cases, a corrosion system may be exposed to radiation field. Most usually, it occurs as a part of atmospheric corrosion, when materials are, besides other factors, exposed also to visible and ultraviolet radiation. Technical significance of corrosion caused by such types of radiation is rather small. On the other hand, metallic materials may be exposed to high energy ionizing radiation ...

Many properties of a material, such as physical shape, crystalline or amorphous form, and particle size, may affect the quality of EPR response. The effects of mechanical treatment to a material such as grinding, crushing, and particle size on EPR signal were reported earlier [1, 9]. The EPR technique is a well known and well established method for dose measurement in several fields like radiat...

The sources of errors associated with the measurement of nuclear radiations includethe noise associated with the radiation pulse, the dead time required for the processing of the incident radiation pulse and the pileup of pulses. In analogue processing, these errors are often downplayed leading to appreciable errors in the observed results. Some digital processors have been designed and built a...

Introduction: Intensity modulated radiation therapy (IMRT) is one of the cancer treatment methods. It is important to selectively aim at the target in this way, which can be performed using a multileaf collimator (MLC). Materials and Methods: In order to specifically irradiate the target volume in radiotherapy to reduce the patient absorbed dose, the use of multileaf collimator has been investi...

gamma rays pose enough energy to remove electrons from atoms of absorbing material including human body and adversely affect human health. the external exposure of human beings to natural environmental gamma radiation normally exceeds that from all man-made sources combined. therefore, we monitored gamma dose rate in indoor environments and estimated corresponding annual effective dose in selec...
