This probably is not a big danger since these calibrating samples were probably emitters of very low levels of radiation. It would appear to me that you would want to be able to pick up the slightest of radioactive particulars so there would be no need for more powerful emitters.
Of course my Nuclear Engineering license was revoked last year.
Radioactive or not, plutonium is also a deadly poison.
