Re: Problem detecting K-40

Lodovico - I have saw cut CsI crystal before, but my experience is that the CsI crystal is fragile and can crumble easily, so it can be difficult but I think possible to make in a home lab. I see CsI crystals of even smaller dimensions available often, but professionally cut. I think you would have ...
