gamma rays can be stop by lead block
No. An alpha particle can
Gamma rays and X-rays will pass right through paper (which will stop alpha rays) and aluminum sheets (that will stop beta rays), but can be stopped by a thick layer of concrete, lead, or other substances having sufficient mass.
Alpha particles are the least penetrating, and are not able to pass through a single sheet of paper. Beta particles can penetrate through a sheet of paper, but not a piece of aluminum. Gamma rays can travel through both paper and aluminum and it takes dense material like lead to stop them or reduce their number. Gamma rays are high energy electromagnetic rays.
Gamma rays, if strong enough, can cause cancer if you are around them too much. There are methods to stop it, though, but gamma rays are hard to prevent. They can be really unhealthy to the human body.
gamma rays can be stop by lead block
It seems that any matter will stop part of the gamma rays; to stop most of the gamma rays from passing, you would need a fairly thick layer of matter. The thickness required to block half of the gamma rays depends on the energy of the gamma rays. Just about any matter will do. For more details, check the Wikipedia article "Gamma ray", section "Shielding".
yes it can stop it
