<p class="MsoNormal">Dear Petra, thank you. I am very interested in hazards in museums , and I had not thought of old x-ray machines , though I have cleaned one, ( the outside of graffitti). What do you consider the dangers are ? There is an oil which is not
so healthy but it is enclosed PCBs. X rays at this time used cobalt 60 , this has a T 1/2 = half life of just over 5 years , thus if we say your machine is 1945 for simplicity . it has had under 16 half lives and we can reckon that after 8-10 half lives
little remains , cobalt 60 becomes safe nickel , I have asked a physics teacher friend of mine for advice too , so I am wondering how dangerous it is . There might be lead and Beryllium that can be dangerous , but they are enclosed

<p class="MsoNormal">The Summerland Museum and Archives Society is looking to dispose of an old dental x-ray machine from the 1940s. We acquired the x-ray machine in 1977 and seemingly no one in our organization thought about the hazards associated with items
of this nature. It has been in storage for a very long time (perhaps even the entire time we have had it) but now we must vacate our storage facility.<o:p></o:p></p>
