Die Behauptung, dass erhöhte Gamma-Strahlung Kamerasensoren beschädigte, stammte von dem damaligen Kodak-Manager Rob Hummel - und die war auch Ausgangspunkt dieses Threads hier, siehe das erste Posting. Hummel wollte damit belegen, dass der fotochemische Film seines Arbeitgebers robuster sei als Digitaltechnik und dass Touristen lieber analog fotografieren sollten. Das war übrigens im Jahr 2011, kurz vor der Pleite Kodaks, und kann daher als Durchhaltepropaganda von der schon sinkenden Titanic abgebucht werden.
Dazu gab es damals schon Richtigstellungen:
"In the presentation, Hummel stated that by killing sensor “transfer pixels,” gamma rays, would deaden an entire row of pixels, producing a black line on every image. If this were happening regularly to air travelers’ digital cameras, considering the number of people flying with them, there would be a ground swell of complaints. To the best of my knowledge air travelers haven’t been making such complaints.
Delving into the numbers, a 2002 study about the effect of Gamma-ray radiation on color CMOS image sensors, like those used in many DSLRs, showed 600Gy (Grays) would kill them, but a 2008 UN report about the effects of radiation on people points out that the average annual effective dose of overall radiation for airline flight crews, including gamma radiation, is only 3.0 mGy (Milligrays)."
Damit ist eigentlich schon alles gesagt.
Nur der Vollständigkeit halber:
"Combined, these studies would seem to clearly indicate the typical digital camera sensor is pretty safe from gamma ray damage when travelers take them on their plane flights to destinations across the globe.
Can gamma radiation kill pixels of digital cameras? Absolutely. This has been known for a long time. NASA’s been using Nikon digital cameras in space for years.
A NASA spokesperson has said, “The space environment (both inside the vehicle and on spacewalks) is tough on the electronic cameras. The radiation damages pixels on the sensor.”
That being said, there is a world of difference, in radiation exposure, at the altitudes travelers fly in commercial jets, even on long distance flights, compared to flying in the Space Shuttle, or the International Space Station.
Since I purchased my first DSLR, a Nikon D70, I’ve flown more than a hundred thousand miles as a travel photographer, and on ***. So far, my digital cameras haven’t had any dead pixels on their sensors.
I think you can bring your digital camera on your next *** flights, and safely expect it will arrive at your destination without gamma radiation damage."
