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 ...
be treated with three types of radiation-gamma rays.high-energy electrons,and X rays-and sets limits on doses,depending on the type of food.The principle is that the dose to be used for a certain type of food should not exceed the amount that is sufficient to kill most harmful insects ...

It's really hard to say, and that's one reason there is controversy about radiation hormesis. We all live our lives bathed in low doses of harmful radiation, mainly from the sun. We get occasional X-rays at the doctor; we breathe radon gas when we're around natural bedrock; we go t...
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 ...
Clustered DNA damage induced by gamma radiation in human fibroblasts (HF19), hamster (V79-4) cells and plasmid DNA is revealed as Fpg and Nth sensitive sites. Nucleic Acids Res 2002;30:3464e3472.Gulston, M., Fulford, J. Jenner, T., de Lara, C. and O'Neill, P. (2...
A gamma counter is a device that measures the gamma radiation in a sample. The main situations in which a person would use a gamma...
“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...
Theelectromagnetic radiationof an object is stretched out slightlyinside a gravitational field. Think of the sound waves that emanate from a siren on an emergency vehicle; as the vehicle moves toward an observer, sound waves are compressed, but as it moves away, they are stretched out, orredsh...
Emerging research suggests environmental exposures before conception may adversely affect allergies and lung diseases in future generations. Most studies are limited as they have focused on single exposures, not considering that these diseases have a mul
