Light photons from red to blue in the visible spectrum have increasing energy. They can be stopped by the aluminum foil of 0. Science Math Social Sciences Humanities. All three radiations can penetrate living cells causing damage. The beta particle travels with the speed almost equal to the speed of light.
Alpha Beta Gamma Radiation
Most of the properties of alpha, beta and gamma particles have been already discussed. Alpha particles are positively charged and so can be deflected by electric and magnetic fields. Thorium is a nucleus that undergoes beta decay. Protactinium is also a beta emitter and produces uranium Gamma rays are highly energetic waves and are poor at ionising other atoms or molecules. Gamma Radiation Gamma radiation:

As far as internal radiation exposure hazard is concerned, the high penetrating power means that the energy released by gamma rays and taken up by a small volume of tissue is comparatively smaller. In most cases, radiation will damage a single or very small number of cells by breaking the cell wall or otherwise preventing a cell from reproducing. Beta Decay Another common decay process is beta particle emission, or beta decay. This means that beta particles are the same as an electron. These have electrons e around the outside, and a nucleus in the middle. Therefore beta a particle has more penetrating power compared to alpha particle they are stopped 1cm thick sheet of aluminum. Let's see how much you've learned:
We talk about "radioactive isotopes" - but what's an isotope? If you think of Dr Bruce Banner, who was poisoned by gamma rays to become the "Incredible Hulk" , the strongest and coolest superhero, this might stick in your memory. This informations are very useful to me and I did understand about three radiation. It has a very small mass and a negative charge. The radioactive isotope measured in carbon dating is carbon, which is produced when cosmic rays act on nitrogen in the upper atmosphere. This translates to the amount of energy actually absorbed in some material, and is used for any type of radiation and any material. However, its short flight knocks about , electrons out of the surrounding atoms.
