Apologies if I am in the wrong section (or even the wrong website!). I am in the UK and have just imported a Fiesta ware vintage radioactive plate from the USA (Ebay item). I have read various reports on the web on the possible dangers from this plate, from "don't worry you get more radiation from a long haul flight", to "these plates leak radon gas from cracks in the glaze which are 7 times the recommended safe level" - I have stored the plate covered with bubble wrap in the cardboard box that it arrived in and put the box in a cupboard drawer away from where I normally sit in the house. My question is - would I be better not enclosing it in a box? i.e. am I in more danger when I take it out of the packaging from trapped radon gas than if I just left it open on a work surface? Will I get a lung full of radon gas when I take it out of the packaging that could be a significant risk? I have a Russian made Krapu dosimeter and it goes well into the red when measuring the radiation on the surface of the plate.
