Not really. If you start looking into 'science' you find that a lot of stuff isn't science. See science is actually defined as this by Mirriam Webster:
"knowledge or a system of knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method."
So things like radiometric dating isn't science, though radiometric decay is science. The difference is you can't really prove radiometric dating is accurate, and there's a lot of proof that it is not (i.e. snail shells that are millions of years old on living snails, seal skins from recently killed seals showing as a billion years old, not being able to date anything that we know the age of etc...etc...). I'm not saying its not accurate, but its not science.
Radiometric decay has been observed, tested, and has been found to never be wrong.
