4 days ago · Irradiance refers to the amount of radiant power per unit area received from a radiation source. In other words, it measures how much energy is delivered to a given area from a specific source. For example, when we stand outside in the sun, we feel its warmth due to the Sun’s energy reaching us. To […]

20 hours ago · The cosmic microwave background ( CMB or CMBR) is microwave radiation that fills all space in the observable universe. It is a remnant that provides an important source of data on the primordial universe. [1] With a standard optical telescope, the background space between stars and galaxies is almost completely dark. However, a sufficiently sensitive radio telescope detects a faint background ...
The human body generally dislikes shutting down anything, because that would likely mean death, or at least a higher chance of dying. Radiation poisoning happens because radiation destroys your cells, and since your arteries and veins are bigger than your nerve cells, there is a higher likelihood of them being hit with radiation, meaning they ...

3 days ago · t. e. The Cambrian explosion (also known as Cambrian radiation [1] or Cambrian diversification) is an interval of time approximately 538.8 million years ago in the Cambrian period of the early Paleozoic when a sudden radiation of complex life occurred, and practically all major animal phyla started appearing in the fossil record.
