lead is a very dense material and can stop most radiation particles, although it is still dangerous as some gamma rays may get through.

Lead can block radiation of all types. This is why lead aprons are worn whenever anyone is undergoing any kind of x-ray procedure. The lead apron protects from the radiation that is generated by the x-ray machine.
By wearing radiation monitoring badges and also protective aprons which are called lead coats.
Lead
The radiation badges tell you how much radiation you have been exposed to so you know when you have been exposed to enough (before it becomes dangerous) and you can stop work in that area until you are able to be exposed to radiation again. They sometimes wear lead aprons to protect themselves from radiation. I think this is right but you had better check again somewhere else because it might not be right.
The material that is most usually used to stop radiation is lead. Lead is composed of large atoms, being a heavy element with a high atomic number, and it is therefore quite opaque to radiation of all sorts. There are many other heavy elements which can stop radiation, however, lead is the most easily available. You can use platinum as well, but it is thousands of times more expensive than lead.
A lot of things, but I think you might be referring to which form of radiation since this is the classic answer as to what would stop Alpha radiation. Furthermore tinfoil would stop alpha and beta radiation and lead would stop alpha, beta and gamma radiation.
The attenuation factor is the main focus in radiation protection. Attenuation is the gradual loss of intensity of a current as it passes through a medium. Lead was found to be effective at attenuating radiation so it became the industry standard. Through research and development, other metals (tin, bismuth, aluminum, barium, and titanium) have been found to attenuate x-rays efficiently while still meeting the lead equivalency.
Technicians (and patients) who are exposed to ionizing radiation (most commonly, x-rays) wear lead aprons to protect their vital organs from radiation. Repeated or prolonged exposure to ionizing radiation has been shown to cause cancer. Lead absorbs x-rays, alpha particles and beta particles. It is much less effective at absorbing gamma rays, but it's far better than no protection at all.
Reduce exposure or lead aprons
every 12-18 months
Yes, the heavy aprons used in the X-RAY room are lined with lead.
