There are various units that might be meant.
The physical unit that all types of decay share is the atoms, with various subatomic particles being produced, but I suspect that is not what you are looking for, which I suspect is a unit of measurement.
One possible unit is the amount of energy released, which is the sum of the energies of the particles released and the difference in the energy of the atom that decays. This is expressed in electron volts, or, more commonly in millions of electron volts (MeV).
Another possibility is that you are referring to the half-life, which is a measure of the time during which a given atom has a 50% chance of undergoing decay. Looked at another way, it is the time during which half the atoms of an isotope will be turned into something else. The half-life is expressed in various units of time.
The element with the symbol Au is gold.
A scientist who studies radioactivity is called a nuclear physicist or a radiologist.

The terms element and compound are used to identify pure substances.
The scientific name of silicon is silicon. Silicon is actually the name of the element that makes up sand. The name comes from the Latin word silex which means flint.
According to my trusted Random House College Dictionary (copyright 1984), this unit is the curie, named after Marie Curie. One curie = 37.0 billion disintegrations per second.

selenium is the element whose name is moon in Greek
The element with the symbol Au is gold.
That element would be . . . aluminum, whose element name is AL. Aluminum is one of the most abundant elements in the world.
Lead (Pb)
Copper. 'Cu' comes from Latin 'Cuprum'.
Gallium, from the Latin word Gallia.
These elements are yttrium and ytterbium.

The word 'einsteinium' is the same, in English and in Latin. It refers to a metallic synthetic element whose symbol is 'Es'. The element has a boiling point of 860 degrees Celsius, and 1580 degrees Fahrenheit. Its atomic number is 99. It has no known use other than radioactivity. For it's either the byproduct of creating, or a step in the production of, other elements. The name honors scientist Albert Einstein [March 14, 1879-April 18, 1955].
