Do you think the takumar 55/1.8 is radioactive? Can always sell me yours... hehehehe

The unit fo radiation leaks is measure in µSV.
I have SMC Takumar lenses and can use my office radiation meter to confirm.
Update the findings next week.
Apparently you can order uranium ore and radioactive isotopes legally in the states without a permit.
Well for one, educational institutions requires a radioactive source for physics experiments and calibration of particle detectors, not to mention people who just love collecting "exotic specimens" such as this for no particular reason.Hi 9V-Orion, not sure why anybody would want radioactive isotopes and uranium ore for. Are there any practical uses for uranium apart from making atomic bombs and creating nuclear energy?
Newuser... read from the web that you can cure the yellowing by sunlight or UV light. Worth a try, or you can enjoy the "natural" yellow filter from the thorium. ;p

it may be radioactive but bokeh is :bigeyes:

I have one of those 1:1.8/55 Lenses. Now I know why my hair is falling out.
Well... it's a good thing you didn't turn into the Incredible Hulk from all the gamma radiation. But not only taks but also from Yashica-Yashinon lenses too. Like those found in the Yashica rangefinders.
Well I am in real trouble then. If the Yashica RF lenses are the same.......
No worries, man. Just enjoy them, life's too short and there are too many unknown radiation in the air now... so perhaps, ignorance is bliss. :bsmilie: That's the main reason why I don't want to research on the existing radiation in the environment now. Might get all paranoid and fearful :sweat:
1) SMC Takumar 55mm/1.8 = 55µSV/hr
No, you received alot more radiation dosage in an intercontinental flight, if online calculators are to be trusted you will be exposed to a total of 223.3 uSV in a flight from Changi, Singapore to Newark, New Jersey.well, is it mean that the takumar's radioactive is pretty high ?
