Three Radium watches

Over the past two days, I've kept three Radium painted watches in my room, having then placed in a plastic box, filled with water, the watches zip locked in a bag filled with water and another two zip lock bags on top of the watches, Upon finding them direct contact with the watches read 5500CPM-6800CPM, currently around the box readings range from 300CPM-680CPM. (I have turned them into the police but they returned them to me after conducting readings and valuing them as safe, they class them as ionising radiation as said by my local police)
