The amount of energy necessary to cause significant biological effects through ionization is so small that our bodies cannot feel this energy as in the case of infra-red rays which produce heat. The ...

Non-ionizing radiation (e.g. heat, visible light) is essential to life, but excessive exposures can cause tissue damage. All forms of ionizing radiation have sufficient energy to ionize atoms and ...

Extreme fire seasons in recent years highlight the urgent need to better understand wildfires within the broader context of ...

Heat energy can flow by conduction, convection or radiation. It always flows from a region of high temperature to a region of low temperature i.e. from hot to cold. Conduction is the flow of heat ...

Scientists consider it the gold standard for evaluating how heat harms the human body ... new risks even for people who escape the sun’s radiation. By 2050, 1.3 billion people will be exposed ...

Ukrainian President Volodymyr Zelensky confirmed a Russian drone equipped with a 'high-explosive warhead' struck the nuclear ...

Probes drilled into Phobos could heat and melt the ice, pump the water into elastic cells that surround a spacecraft, and shield a crew from radiation. More radical solutions for radiation have ...

Climate scientists present a realistic supercomputer simulation that resolves the complex interactions between fire, vegetation, smoke and the atmosphere. The authors find that increasing greenhouse ...

Light, heat, radio transmissions, and medical X-rays may not seem all that similar, yet they are all forms of electromagnetic radiation—waves moving through space (not just outer space ...
