Aims The effects of irradiation (gamma-rays and electron-beams), up to 10 kGy, in the antimicrobial activity of mushroom species ( Boletus edulis , Hydnum repandum , Macrolepiota procera and Russula delica ) differently processed (fresh, dried, freeze) were evaluated. Methods and Results ...
In this article, we'll find out exactly how X-rays machines pull off this incredible trick. As it turns out, the basic process is really very simple. Contents What's an X-Ray? The X-Ray Machine Are X-Rays Bad for You? What's an X-Ray? X-rays are basically the same thing as ...
beta particles, gamma rays and neutrons. Alpha and beta particles would mostly be harmless. Although they're fast-moving particles, they're too big to pass through much matter -- alpha particles (heliumatoms) can be stopped by a few inches of air or a piece of paper, and beta...
Gamma rays and cosmic rays are high-energy particles and radiation that originate from various sources in the universe, such as supernovae, black holes and even the Big Bang itself. Scientiststheorizethat antimatter should be as abundant as ordinary matter because of the Big Bang, but it's sc...

The kinds of radiation we're talking about are alpha particles (two protons and two neutrons joined together, so they're like the nuclei of helium atoms), beta particles (electrons traveling at high speeds with high energy), and gamma rays (very high energy electromagnetic rays—a bit like ...
What speed do gamma rays travel at? How fast is the speed of light in gelatin? What is faster than the speed of light? What is the speed of light in a vacuum? What is the speed of light in a vacuum in mi/s? What is the speed of light in kilometers per hour?
Why do X-rays and gamma rays have equivalent RBE values if they provide different amounts of energy to the body? a. Penetration distance, which depends on energy, is short for both X-rays and gamma rays. b. Penetration distance, which depends on energy, i Discuss the risks and benefits...
It is often useful to detect gamma-rays from electromagnetic transitions in the final nucleus, both to improve the precision and resolution of the excitation energy measurements and to assist in the identification of the observed levels. Several aspects related to gamma-ray detection and angular ...
But how do we get the sails and their spacecraft into space? Let's take a look. You want holes in the sail? Les Johnson, of Marshall Space Flight Center, holds a rigid, lightweight carbon fiber material that gave many solar-sail-scientists pause for thought. This fiber was a departure...
