It is hypothesised that Se deficiency, as it occurs in several parts of the world, may aggravate harmful effects of ROS-inducing stressors such as ionising radiation. We performed a study in the newly established LDR-facilityFigaroon the combined effects of Se deprivation and LDR γ exposure ...
Ionising radiation also produces free radicals that can cause clustered DNA lesions. These types of lesions occur when at least two radical hits occur within 20 base pairs26 and are assumed to contribute to the harmful effect of radiation. This is partly due to the compro- mised repair of ...
Why is electromagnetic radiation harmful? Why can electromagnetic waves travel through space? Why do electromagnetic waves travel at the speed of light? How does electron capture release gamma rays? Why can electromagnetic radiation travel through empty space?
Most non-ionizing radiation, such as radio and microwave energy, is considered harmful only to the extent of the amount of heat energy it transfers to whatever it hits. This is, in fact, the way that microwaves cook food. UV light is unique in that while it is non-ionizing, it does ...
It absorbs and, in many cases, emits electromagnetic radiation in the form of gamma rays, visible light, infrared, and more. It can generate magnetic fields of various sorts and strengths. Matter has mass, creating the force of gravity, the effects of which can be readily observed. All ...
Ultraviolet radiation is usually used to disinfect the inside of a biological safety cabinet between uses. X-rays are used to sterilize large packages and pallet loads of medical devices. Gamma radiation is commonly used to sterilize disposable medical devices (such as syringes, needles, cannulas,...
“They’ve known about this since the development of the gamma-ray log back in the 1930s,” says Stuart Smith, referencing a method of measuring gamma radiation. A New Orleans-based lawyer, Smith has been trying cases pertaining to oil-and-gas radioactivity for 30 years and is the ...
Why do scientists use synchrotron radiation? Why is electromagnetic radiation harmful? Why does ionizing radiation damage cells? Why is the sun a source of non-ionizing radiation? Why does ionizing radiation disintegrate the body? Why is gamma radiation ionizing radiation? What are the dangers of ...
harmful, but even here there are exceptions depending on the geological formation history and mineralogical composition. The highest activity index of 1.87 was determined for the gneiss Giallo California. Model calculations to determine the expected radiation exposure for a human were used by applying ...
Gamma decay: This is the release of gamma radiation from natural radioisotopes. Usually, gamma decay follows alpha or beta decay where the daughter nucleus is excited and falls to a lower energy level with the emission of a gamma radiation photon. However, gamma decay also results fromnuclear f...
