is the antiparticle of the electron; when brought together, two such particles will mutuallyannihilateeach other. Gamma rays are electromagnetic radiations such as radio waves,light, and X-rays. Beta radioactivity also produces the neutrino and antineutrino, particles that have nochargeand very littl...
4– Radiation in Chernobyl is relative Radiation comes in many forms. In science, radiation falls on a spectrum of electromagnetic radiation. Long wavelengths are things like radio waves. Light is somewhere in the middle. Small lengths like alpha, beta and gamma rays are emitted from radioactive...
Alpha and beta decay are generally slower processes than gamma decay. Half-lives for beta decay range upward from one-hundredth of a second and, for alpha decay, upward from about one one-millionth of a second. Half-lives for gamma decay may be too short to measure (around 10-14 second...
These days, flyers are simultaneously irradiated by: airport radar installations, airport body scanners beaming experimental millimeter waves; in-plane microwave communications systems; cosmic ionizing radiation and high counts-per-minute of beta, alpha and gamma radiation, which reportedly pollutes the upp...
NASAhas a strictlist of criteria for nuclear batteries. The fuel must be safe, in case of a launch accident. It mustn't release too much beta, gamma, or neutron radiation, because they interfere with equipment. It must be stable because you don't want it to explode. It must have a ...
This puck came as part of a nice, well-made set of slides made from various thicknesses of aluminum and lead, obviously meant as an educational tool to teach people the difference between alpha, beta, and gamma radiation. Generally speaking, gamma radiation will be partially stopped only by ...
NGC 4148is a Blazar, these areActive Galactic Nucleior AGN for short. They are usually young galaxies in deep space where they emit radiation from their centres. Blazars are a form ofQuasar, the difference being the angle in which the radiation is being emit ed. A Blazar has the emitting...
As if the potential for fiery crashes and hijackings weren’t enough reasons to fear flying, we also have to worry about increased levels of radiation. High altitudes offer less atmosphere to shield us. And, unfortunately, the body of the aircraft does little to protect us from the shower ...
120. The afterglow of the Big Bang can still be detected as microwave background radiation coming from all over space. 121. Dishes in the space telescopes have to be made accurate two billionths of a millimeter. 122. You can see another galaxy with the naked eye: the Andromeda Galaxy, 2....
The chain reaction grows, resulting in heat, light, and nuclear radiation in the form of beta, alpha, and gamma rays.So How Does The Bomb Reach Critical Mass?The Hiroshima bomb, called Little Boy, used two separate masses of U-235, one to act as a projectile, the other the target....
