A long, very comprehensive, and quite worrying forum message about radioactive lenses.
Sorry, it's italian, but with an online translator you may be able to at least get the overall meaning - and for specific passages, you can ask me:
http://www.photo4u.it/viewtopic.php?p=1530804&sid=c5ec04985b78ebb71e494ca5efa4220f
(I will put the link in the Links forum for a more permanent display)
it seems that not only the well known ones (such as the SMC Takumar 50/1.4) are radioactive. Most of our manual lenses are, especially Nikkors and Leicas (especially Leica Ms). And - to my surprise - it seems that also some Canon EF lenses, still are!
And, it seems that in the SMC Takumar, the back lens actually has Uranium traces in it.
Well, until I read this, I used to keep some lenses in my bedroom (more casually than for a reason). Now, they will go off, and be stored in some place where I know neither me or other people is going to stay for a long time nearer than 2-3 meters.
And I have to lose that habit of keeping a lens next to the computer and play with it while I am working, as a distraction! _________________ Orio, Administrator

It should be noted that even for a _serious_ photographer the dose received from a radioactive lens is rather insignificant,
an insignificant fraction of the natural background radiation. Smoking one cigarette per day gives
a larger extra radiation dose due to the radioactive polonium contained in the tobacco.

It is indeed. The older super-takumars (serial below around 1.4million -i've managed to come to this number after looking to several auctions on eBay; the external differences are subtle) are not radioactive and are -never- yellow. There's explanations and solutions for the yellowing on the internet. I've been trying to buy one of those old takumars so that I won't have a yellowed and radioactive lens, but I think maybe the coating is not nearly as good as the later SMC takumars.
Of course, some lenses are more radioactive than others. I once came across a website where they had measured several different lenses and i've read opinions from some doctor somewhere else... Even if the amount is quite small, it is certainly measurable (several meters apart for the most radioactive lenses) and those lenses are not something you want to keep on your pocket 24/7. I wouldn't even keep them in my desk or in my room all day, just to be safe. |

Why would an X-ray machine have a radiactive source inside it?
X-ray machines use a Walton-Cockroft multplier curcuit, fed from AC, to produce high voltage D.C....Typically, up to 150,000volts, a radiocative scorce is not required to produce the X-rays...If they do have a source, then perhaps the source is used to calibrate the machine somehow? |

Yet another post in this forum about lens radioactivity? There are already so many here. We are lucky to have now several members who have performed tests using sensitive instrumentation which prove that radiation from lenses is in many cases less than that of the radon gas emitted by bare earth.
The only worrisome lenses are those that were used by government in nuclear research and energy facilities which may have been contaminated with radioactive dust -- these were sold through government surplus auctions.
Super, S-M-C, and SMC Takumars have some thorium in one or more of the coatings, iirc, used for refractive properties. Thoriated glass is used in some other lenses for refractive properties.
Some reactor waste products are used in inexpensive x-ray machines in US, probably elsewhere in the World. Some metal products made in China and elsewhere using recycled metals which do contain trace amounts of radioactive substances, such as silverware and jewelery, have been shown to have significant 'hot spots'.
If lenses are so radioactive where are reports of fogged film?
On my to do list is to attempt to photograph patterns of radioactivity using same principle as in Spinthariscope -- the patterns may perhaps be very beautiful! _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

Are there any examples? I have heard people tried that method without positive results because level was too low (or perhaps time too short).

Some people simply took unexposed film in black plastic bags and place lenses on top for some time, then developed it.
A highly overrated topic, we have way too often discussed here. |
Are there any examples? I have heard people tried that method without positive results because level was too low (or perhaps time too short). I am thinking a thin sheet of calcium fluoride may show collisions bright enough for a photo... |
It takes several days of exposure!! _________________ Klaus - Admin
