With a meltdown, the fuel turns to liquid and then burns through the containment vessel, spewing radiation far and wide. In 1979, Three Mile Island's Unit 2 came perilously close to this scenario, with the core partially melting down and flowing to the floor of the containment vessel. ...
How far can gamma rays travel in air?Gamma Ray Air Penetration:Gamma rays are highly energetic electromagnetic waves that are part of the electromagnetic (EM) spectrum. Their associated short wavelengths (in the picometer or smaller range) and high frequencies (in the exahertz (EHz) range or ...
What are the physical effects of space travel? Human beings have been through millions of years of evolution to become perfectly adapted to life on Earth, so spending time in space - with no gravity, no sunlight and different levels of radiation - poses a r...
Polaris Days through parts of Earth's radiation belt, providing the chance to better and radiation affects the human body.After the five-day mission, on September 15, the Polaris Dawn crew landed Florida US.NASA described the mission as "a giant leap forward" for the industry. It also ...
A robotic drone that can travel through air and water, and also attach itself to larger objects with a suction cup, could be useful for tagging wild animals, say its creators. The suction cup is inspired by theremora fish, which attaches itself to larger marine creatures in a symbio...
Specifically, radiation oncology contributes significantly through patient transportation for daily treatments. This study quantifies GHG emissions from external beam radiation therapy (EBRT) in the U.S. and explores emission reductions via hypofractionation treatment schedules. Materials/Methods Employing a ...
its eerie clicks signifying the presence of dangerous ionizing radiation. More recently, doctors embraced sound to indicate specific medical readings; the beep-beep of an electrocardiogram is perhaps the most iconic (unless you count Monty Python’s medical device that goesbing!). Current applications...

a specified error tolerance. The solution to the monochromatic RTE allows the simulation of both narrowband (quasi-monochromatic) and broadband radiances. We do not consider the polarization state of ground-reaching radiation because most devices employed in night-sky monitoring are designed to average...
