Whale tooth ID help

[Bobakman]

I need help identifying this fossilized whale tooth. It is slightly radioactive. I purchased it in a store on the West Coast of Florida. 
It’s origin is not really known but the store owner told me that all the items were purchased from a single collector in Florida so it’s possible the origin could be from somewhere in Florida. 
My apologies I did not have a metric ruler on hand.

I believe this is Scaldicetus sp.

Possibly Sperm whale

Yes, Scaldicetus.. What do you mean "slightly radioactive"   and how does the seller know that?

Some whale tooth fossils can be radioactive due to the uptake of uranium from groundwater. Perhaps the seller had it tested with a Geiger counter.

Yes using a RadiaCode scintillator It was verified to be radioactive.

Many of the ground water Wells in Sarasota county in Southwest Florida are actually radioactive containing radium 226 easily measured at the water softener since it concentrates there using my Radiacode device. 
I also have a megalodon tooth as well that is slightly radioactive.
