Answer 2

Firstly, you need to know better about the subject. The gamma radiation that you read in history is a consequence of mass-energy relation E=mc^2 that occured during the fission. The KE is due to bombartment of particles very similar to two snooker balls colliding with each other and nothing else. The total mass of products after the reaction is less than the total mass of reactants before the reaction. This is called mass-defect and this is where E=mc^2 is applied giving out gamma radiations.

Answer 3

Alpha particles are He nuclei. They are typically highly energetic and are highly ionizing but don't readily penetrate materials. Alphas can be stopped by a few inches of air, or by your epidermis. Since they are charged, they can be influenced by electromagnetic fields. If alpha emitters such as radon are internally deposited into, say, your lungs, the alpha particles can cause significant damage.

Beta particles are electrons. They have moderate penetration and are moderately ionizing. Like alpha particles, they can be affected by electromagnetic fields. A thin sheet of aluminum will block beta particles.

Gamma rays are photons. They are weakly ionizing but quite penetrating. High-energy gamma rays will pass completely through your body, leaving a wake of ionized or even dissacociated atoms (or DNA) behind them. Gamma rays have no charge and are not affected by EM fields.

Answer 4

alpha=helium nucleus, +2 charge, mass of 4
beta=electron from the nucleus,mass zero, charge negative
gamma=electromagnetic ray of very small wavelength and high frequency, no mass, no charge
