Going back to the nuclear chat. That yellow pen looking thing is an old instant read dosimeter. It is an evacuated glass tube that you apply a high voltage charge to as it gets hit by radiation the voltage drops. To read it you can look through it at a light and see a tiny needle that tells you the dose or more accurately by putting it back in the charging base and read out the voltage. Pretty much every time someone retires at work we find those in desk drawers or lockers. They used to cost a shitload of money. They are incredibly obsolete as newer electronic EPD's have far better accuracy and can read low doses. Working in the nuclear industry you see so much obsolete technology but I can't say I have run into much failed technology. Here is one I would love to see go. Meet Snoopy the neutron radiation detector. It is huge and heavy and has been the standard since the 1940's. Typically used in areas were you don't want to spend alot of time lugging heavy poo poo around in. http://www.fusor.net/board/view.php?bn=fusor_neutrons&key=1070060131

We had all of our controlled documents on microfiche until recently. Ironically the week after the cards were removed a power outage shutdown access to the servers that have the digital copy's.
