To be honest,I would not rely on cpm for a measurement, particularly with radium. The radium is a particle radiation and this cannot penetrate the skin. It has to be ingested (i.e. inhaled) to have an affect. A more reliable measurement of this kind of radiation is the Sievert, which, roughly, is the affect of radiation. Broadly speaking, when dealing with radium, precautions such as breathing equipment and removing radium in a fluid is advised. Disposal is also something to consider. It's generally a pain in the arse to dispose of and you are better just leaving it undisturbed -
I tried burning them, but they create a lot of smoke. So I collect them in a plastic container, and in the summer put them in an open container in the garden and let them evaporate.

From Bestfit and Ranfft so think it worth a try getting this balance staff. https://ranfft.org/caliber/2333-Damas-23-Beguelin-BTC What measurements can you get from the broken staff?

I keep the big containers the fluid is shipped in to pour the old fluid back into. My local tip has a chemical disposal section. I drop them off there. It's free at my tip -

A point with regulation, when you see a large time variance between horizontal and vertical positions is that this is often due to the spacing of the regulator pins, not the hairspring itself (although a kinked or misshapen terminal curve can cause regulator issues).
