Lead is most commonly used for protecting people from radioactive substances.
For example, if you go to the dentist and they give you an X-ray of your teeth, they will usually give you a lead bib to protect you from the radiation produced by the X-ray. However, carbon (graphite usually) can also be used to shield, but whereas a plate of lead may work it would take a brick of graphite.
Lead is commonly used as a shield to protect people from radioactive substances. It is dense, so it effectively absorbs and blocks the radiation, helping to minimize exposure to harmful radiation._lead
Radioactive elements are unstable and will decay into other elements in a decay chain. Non-radioactive elements are stable and won't commence into radioactive decay. Radioactive elements can be found from atomic number 84 onwards.
Promethium, a radioactive element, does not have a distinct smell. It is typically stored in a sealed container due to its radioactivity, so people do not come into direct contact with it and experience its smell.
Hassium is a synthetic element that is primarily used for research purposes in scientific studies. It has no practical applications outside of scientific research due to its unstable and radioactive nature.
Nope. Gold is none of those, and is otherwise inert, too. That is why gold is often used for people's tooth crowns, and as electrical contacts in electronics. Gold does not even corrode or "Rust".

* Alpha radiation can be stopped by a sheet of card * Beta radiation can be stopped be a few inches of aluminium * Gamma radiation can be stopped by several inches of lead or many feet of concrete.
Usually lead is used for shielding, however I believe Boron is used to in a sense "neutralize" radioactive material. I believe this was discussed in possible solutions for Fukashima
Lead is most commonly used for this. An example is the lead jacket the put over you when you get an x-ray at the dentists'.

Thorium can be dangerous, especially when powders are inhaled, because is a radioactive element.
No radioactive substances are used for ordinary greenhouse work beyond what is found in nature. Radioactive substances are controlled very closely by governments - in the US, it is done by the NRC. Licencing and training are required to work with such materials. They are not the sort of thing workers would encounter without being told. There are radioactive substances found in nature, but the level of radioactivity is usually considered insignificant, and they are nearly always no different than levels people might encounter in any ordinary workplace or home.
The most used is lead.
Most people use a ceramic mat.
