dbeids Posted June 21, 2022 Share #1 Posted June 21, 2022 Advertisement (gone after registration) The Leica manual has a warning about sensor damage from airport X-ray scanners. What are peoples experiences please? In the film days I asked for hand inspection. Is that necessary.? Quote Link to post Share on other sites More sharing options...
Advertisement Posted June 21, 2022 Posted June 21, 2022 Hi dbeids, Take a look here Airport X-ray machines and M10 monochrom. I'm sure you'll find what you were looking for!
Anakronox Posted June 21, 2022 Share #2 Posted June 21, 2022 No issues in over 2 years with my M10M and it’s gone through at least 50 scans in that time. I wouldn’t worry. Quote Link to post Share on other sites More sharing options...

Al Brown Posted June 21, 2022 Share #5 Posted June 21, 2022 (edited) Apart from the usual moisture, chemicals, static discharge or (electro)magnetic fields warnings under SAFETY REMARKS I cannot find it either... Uh but it does say cosmic radiation may cause pixel deffects 😊 Edited June 21, 2022 by Al Brown Quote Link to post Share on other sites More sharing options...
dbeids Posted June 21, 2022 Author Share #6 Posted June 21, 2022 My inaccuracy. . Turns out the warning relates to “cosmic radiation” during air travel not the scanners. It’s in the early general warning pages. Quote Link to post Share on other sites More sharing options...

NigelG Posted June 21, 2022 Share #9 Posted June 21, 2022 IMHO it’s a bit of a moot point which radiation it refers to as if it’s going through an x-ray machine you’re likely boarding a plane and then getting cosmic radiation… FWIW my M9M / 240-P and 2 Edition 60s have been through machines and on long-haul flights maybe 15 times a year over the last few years and I don’t really even think about it - I was much more concerned with the scanners in film days. I wonder whether it’s more of a hypothetical concern than a noted phenomena but I’m happy to be corrected. I think that the exposure is rated about 50x to 100x on a high-altitude long-haul flight compared to ground level background radiation , but given the duration it doesn’t really add significantly to the “lifetime” exposure of the sensor.

Al Brown Posted June 22, 2022 Share #10 Posted June 22, 2022 Everybody everywhere has a choice/option for an "opt-out" from any scanner and to be hand searched by TSA and other airport authorities, no given reasons necessary. One just has to inform the staff immediatelly after putting everything on the belt. Quote Link to post Share on other sites More sharing options...

"What is the difference between cosmic radiation and x-rays? In common scientific usage, high-energy particles with intrinsic mass are known as "cosmic" rays, while photons, which are quanta of electromagnetic radiation (and so have no intrinsic mass) are known by their common names, such as gamma rays or X-rays, depending on their photon energy." - from Wikipedia Flying imaging sensors at high altitude (and in space, beyond the atmosphere) definitely exposes them to cosmic radiation damage, where the mass of the impacting particles can actually break things in micro-electronic devices, even if the incidence of such damage is relatively limited, in practice, within the atmosphere. This is why electronic imaging systems used in space have to be specially 'hardened' for the task and in situations where there is limited atmospheric/magnetic field protection (the Moon, Mars, etc). I've not seen much evidence of damage on any of my consumer digital cameras either, I just wanted to point out the fundamental difference between the x-rays used in scanners and cosmic radiation. ALL digital cameras (and other micro-electronic devices, never mind living tissues...) are susceptible to damage by cosmic radiation due to the mass of cosmic radiation particles. There is, of course, nothing you can do to 'opt out' of cosmic radiation exposure aside from not flying in high altitude aircraft...
