Oct 17, 2014 at 22:59 | comment | added | CuriousOne | @Omen: Let us know when you get a reply. I would love to know if there is a useful dynamic range. Not that they will let you take a phone inside a CT... and then there is also the question if the phone would actually continue working. | |
Oct 17, 2014 at 22:57 | comment | added | user60063 | No, I did not notice any information about an upper limit either. I am thinking of writing to them asking about this. | |
Oct 17, 2014 at 22:56 | comment | added | CuriousOne | @Omen: Thanks for the plot, it's quite interesting. Now, where this may work, though, is during a medical x-ray. Does the source give a limit for saturation? I didn't see it. After all, during a CT we are talking about many times the max. annual dose delivered in a few seconds, so the problem for the camera may be that it goes all "white", with no useful information about the total exposure, either. | |

Yes, in the webpage, they state The dose rate at which the phones can accurately calculate the dose rate is equivalent to 0.2 Sv if exposed for an entire year - there is definitely a limitation.
