I wanna take it because I like the focal length and I don't have a substitute. I haven't travelled with it before and until a couple of days ago I had never even heard of radioactive camera lenses. Who knew? The whole screening process through customs seems to be getting rougher and rougher each year and I just wanted to do my due diligence. I've been waiting for a year for this vacation, first one in ten years without the children. I'm sure those of you with kids would understand why you wouldn't want to do anything that could even remotely jeopardize that!

If there was any jeopardy then there would have been a lot of warnings over the years about using these lenses, so far in over 50 years of photography I've never seen one.

Thinking logically radiation badges use film and measure the the increase in base fog, so if the lenses were hazardous they'd fog film if left on a camera loaded with film and that just doesn't happen.

Carry a smoke detector, or anything glow in the dark to mask it, these are also slightly radioactive

That's enough reason for a whole new camera kit. Seriously though, the radiation emitted by (very few of) the Takumars is very low-level Alpha radiation and won't penetrate an aluminum lens cap, so get one of the original press-on aluminum lens caps or get a threaded screw-in aluminum cap and they won't ever know unless they take the cap off and stick a Geiger counter element in there, which they won't because nobody funds their border patrol or customs services well enough to provide agents with Geiger counters.

Buena suerte and enjoy your vacation.

Serious Glass, it wouldn't have been Wheaties (that would have been Superman). Either Kix or Cheerios. Because each program had only one sponsor, believe it or not the sponsors were closely associated with the programs. Something unbelievable for later generations:we taped our dimes and quarters onto the box tops with scotch tape as well as taping our name and address and the box tops apparently arrived intact at their destination. Try that now!

A little knowledge is dangerous, Brazil nuts are more radioactive than your lens, don't sweat the small stuff http://mentalfloss.com/article/63768/7-most-radioactive-items-your-home

and according to Dr House, they also contain selenium, enough selenium that if you
are hold up eating brazil nuts for an extended amount of time, you might get selenosis ...
(which presents itself like radiation poisoning)
if that happens, you just need to drink a tea made from steeping some sort of exotic bug larvae
this should answer any questions you might have

I've taken an Industar 61 L/D on a plane with no issues ... and it's radioactive and communist.

The only time I have ever had issues with air travel is one time when I tried to smuggle and Bloody Mary with a piece of lime into Hawai'i.

There are rules regarding transportation of radioactive substances.


However, generally those rules are looking at radioisotopes as used in industry and education. What you need to do is check the TSA and carrier rules for transporting radioactive materials and they will almost certainly mention activity in sieverts (or milisieverts, microsieverts). Substances with an activity over a stated minimum will be subject to special rules/regulations. Substances which emit ionising radiation under this level will not.


Chances are your lenses are not radioactive enough to warrant any interest. But you can check...someone must know the likely activity of the substances in your lenses. Or find someone with a Geiger counter to measure it (local school, college, or local nutcase like me).


Everything emits some radiation....the ground, bricks, yourself...you will be exposed to more in the aeroplane for a few hours as the clouds and atmosphere protect us from most of the sun's radiation. For this reason airline pilots must retire after fewer years service than desk clerks and astronauts have their exposure to radiation rigorously monitored.
