Please tell me I haven't been sleeping next to an incredibly poisonous radioactive rock [Xenotime] for months.

I love rockhounding and picked this fucker up by an old mine. I got fucking arsenic poisoning. Currently on strong ass. What do I do, Anons? Is this truly Xenotime and if yes, should I get a lead box for it asap? All signs point to this rock being the cause of my problems and it would be irresponsible to just huck it back outside where another dumbass like me might go 'ooh, weird rock what the hell is that?'
