What are 3 types of radiation and what they are made of.?

Answer 1

The three types of radiation

Alpha radiation consists of particles with two neutrons and two protons in it. Just like the kernel of Helium. This means, that the mass of the particles is very big, compared to other nuclear particles. Therefore, alpha radiation is easily absorbed by air. It reaches only some centimetres far. But if such a particle reaches biological tissue, it impacts with large energy and therefore is very dangerous.

Beta radiation consists of electrons. Just those electrons, which normally flow through a copper wire, when you switch on your lamp or radio. But when it is output from an atomic nucleus, it is kicked off with high energy and penetrates organic material without problems. But it is easily absorbed my most metals.

Gamma radiation is different from the above radiation, in that it does not consist of particles. It is some kind of light, but light we cannot see. You know, there is light you cannot see. Think of "black light", which is ultraviolet light, that turns white shirts to shining blue white in discotheques. But as gamma radiation emerges also from the nucleus of atoms, it is full of energy. It contains even more energy than X-rays, which penetrates organic substances, but is considerably absorbed by more dense organic compounds like bones. Gamma radiation contains so much energy, that it easily passes metal. You will never succeed to completely absorb gamma radiation even not by plumb or concrete walls. But you will be able to absorb the most of gamma radiation, if you use an absorber thick enough.

You might assume, that gamma radiation is the most dangerous of the three types of radiation for human health. But you are wrong. The most dangerous type of radiation for human health is alpha radiation. Because the impact of alpha radiation to organic tissue causes big effects, it is very dangerous to incorporate alpha radiation emitting compounds with food.

Answer 2

3 Types Of Nuclear Radiation

Answer 3

Radiation in general is made up of power. The differences of radiations is in the frequencies. the higher the frequency the greater the power of radiation. To calculate the energy of the radiation falling on a surface you have to multiply the power by the amount of time that the radiation is hitting the surface.
Radiation stemming from unstable atom is described by their power level as a function of frequencies.They are; [1] gamma radiation which is the most penetrating;
[2] beta radiation ,[3]alpha radiation which is the least penetrating.

Another is X ray radiation.
The others are radio wave radiation,visible light radiation,Heat radiation down to infra red.

Answer 4

The 3 types of nuclear radiation are alpha(a helium nucleus), beta (an electron and gamma which is a very high energy ,highfrequency, small wavaelength, ray.

Answer 5

1) Alpha Particles which are simply Helium nuclei ( Two neutrons and two protons)
2) Beta particles which are nuclear electrons - high speed electrons formed on the spot in the nucleus when a neutron changes into a proton.
3) Gamma rays. A form of high frequency electromagnetic radiation.

Answer 6

Three most common types of radiation are alpha, beta, and gamma. Each of these occur naturally from the sun and can occur via man-made devices as well. As far as destructive power in human tissue one rad is equivalent to 1x10 to the (-2) J per kg of tissue. Alpha has approximately 10 rads, Beta has 1rad and gamma has 5 rads as determined by their molecular size and energy outputs. Hope this helps

Answer 7

Well, visible light provides information about the distances of astronomical objects, because you can measure their relative brightnesses compared to standards "candles", and their redshifts. Gamma rays and x-rays give us information about high-energy objects like pulsars and black holes. Radio waves can penetrate dust, so they can tell us about the center of our galaxy, and detect cosmic background radiation. But of course every part of the EM spectrum gives additional information, so you better double-check with your class material.
