Toshiba’s Portable Gamma Camera detects radiation hotspots

by ruchi

Toshiba has developed a Portable Gamma Camera which overlays color-coded radioactivity measurements over visual images. It is a more refined version of a similar concept which was tested and proven at the stricken Fukushima Daiichi nuclear power plant. At the first sight it looks like a sophisticated piece of camera which can take photographs. But it does much more beyond that. The on-board radiation sensor translates numerical readings into color-coded pixels i.e. green to red and overlays the colors onto each photograph. There’s also no film, disc or SD-card upon which to record the composite images. These are instead relayed to an assigned computer, laptop, tablet or other such display.

Toshiba calls it portable but that doesn’t mean you can actually tote it around in bag. It weights as much as 9.8kg and measures 380 x 110 x 241mm (15.2 x 4.4 x 9.64 inches). So it’s safe to say that it is ‘relatively’ portable when compared to the brute used at Fukushima.
