Write the composition of Alpha, Beta & Gamma Rays. |
|
Answer» Alpha and Beta particles are actually physical particles of matter. The Alpha is two protons and two neutrons, and consequently is relatively very heavy and slow and carries a double positive charge.. A Beta is simply an electron and has a negative charge. The Beta may be moving from very slow to very fast, and the speed is an indication of it's "energy level". Gamma Radiation is a true electromagnetic energy, and moves at or near the speed of light. Alphas can barely penetrate anything, not even a piece of paper. Betas do a bit better but still can only penetrate a thin piece of aluminum. Gammas on the other hand can penetrate inches of lead and feet of most other things. |
