Do chemical bonds affect radioactive decay rates?

[sniffer]

is there exists radioactive compound, such as uranium compound with some other elements? does the bonding of atoms into molecules make radioactive decay more difficult? causing "screening" effect for example?

thanks.

Radioactivity is wholly a property of the nucleus and is independent of the compound in which the radionuclide is present. The rate of nuclear decay (transformation) is the same regardless of the compound.

See - http://www.webelements.com/webelements/elements/text/U/key.html - which has a list of U compounds to the right and down.

The independence of nuclear decay from chemical compound form applies to all elements.

thanks a lot.
