Ultraviolet radiation also has positive effects on the human body, however. Itstimulatesthe production ofvitamin Din the skin and can be used as a therapeutic agent for such diseases aspsoriasis. Because of its bactericidal capabilities at wavelengths of 260–280 nm, ultraviolet radiation is useful...
Radiation is the emission and transmission of energy in the form of electromagnetic waves or particles. Radiation can be ionizing or nonionizing radiation, and only ionizing radiation has enough energy to potentially cause damage to cells and DNA. Sources of radiation include natural phenomena like ...

we need to worry about on a daily basis. However, sometimes unexpected events can make our fears of radiation sickness seem all too real. We're going to explain exactly how radiation causes radiation sickness, how much radiation will make you sick, and what effects different dosages can have...
Type:Non-ionizing radiation Sound waves with higher frequencies (higher than what humans can hear) are called ultrasound. It is similar to the normal (audible) sound in terms of physical characteristics, except that it has frequencies higher than the upper audible limit of human hearing. ...
1 Since the discovery of X rays in 1895, ionising radiation has been a part of our life and consciousness. From the very beginning, radiation has been shrouded in myths-of exaggerated expectations as well as excessive fear'. Radiation has been characterised partly as a life force, partly as...

This technology has been applied to microorganisms’ inactivation in juices, fruits, vegetables, meat, and others. Still, UV radiation also can negatively affect the food products’ quality. UV radiation accelerates the oxidation of fats and oils. It also affects vitamins (A, B2, B12, D, E,...
The loudness, or intensity, of sound is measured in decibels. For each increase of 10 decibels, the sound wave has 10 times as much energy. For example, a sound of 20 decibels is twice as loud as one of 10 decibels, but has 10 times the energy. The softest sound humans can hear, ...
Ionizing radiation has been pivotal in cancer therapy since its discovery. Despite its therapeutic benefits, IR causes significant acute and chronic complications due to DNA damage and the generation of reactive oxygen species, which harm nucleic acids,
