Heat dominates conversations among Malayalis these days. And the term ‘heat wave’ has become part of common parlance, as the ...

By design, the detonation of a nuclear weapon in a major city would be devastating. The explosion of intense heat and radiation would kill tens of ...

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 ...

The radiation directly heats up the ground, instead of warming the air. This permits surfaces such as roads, sidewalks, and other hard surfaces absorb heat, which in turn melts ice and snow.
