Alpha, Beta and Gamma Radiation

Three forms of radioactivity.

Alpha Radiation

Beta Radiation

Gamma Radiation

Alpha particles: positively charged subatomic particles

Helium atom nucleus made up of 2 protons and 2 neutrons ejected by some radioactive elementsToo big to penetrate solid surfaces

Speed and mass give it enough energy to damage surfaces (i.e., skin)

High-energy radiation emitted by the nuclei of radioactive atoms

No electric charge

Can penetrate most solid materials (except dense materials like lead)Damages body cells; more dangerous than alpha and beta radiation

ActivityActivityPretend you have been given 3 radioactive rocks; 1 alpha, 1beta and 1 gamma. You can get rid of one rock, pocket another and hold the last one. Which would you throw away? Pocket? Hold? Turn to your neighbor and discuss the answer to this question. You have three (3) minutes.

There are three forms of radiation. Alpha radiation cannot penetrate solid surfaces and causes the least amount of damage to the body. Beta radiation can pass through light surfaces and can harm body cells. Gamma radiation can pass through most solid surfaces and damages body cells.

Create your own Create your own radiationradiationUsing only the materials in the beaker, you are to create atoms and demonstrate them going through all three types of radioactive decay. Keep all materials on the placemat provided.

In the center nucleus: Red Legos- Protons White Legos- NeutronsYellow Legos- Gamma rays

Beans- Electrons (e-)

Use the periodic table to determine # of protons, electrons, neutrons.

Make elements 1-10 with each going through:Alpha decay- remove 2 protons, 2 neutronsBeta decay- remove one neutron, add a proton, give off an e-

Gamma decay- give off gamma ray-no change in massDemonstrate to another student this process, obtain a signature for all 10 atoms going through all three forms of radiation.
