The device can incorporate results of gamma radiation measuring within 10 meters into a picture taken by a built-in camera.

The image can be checked connecting the device to a computer, Hitach said Sunday.

According to Hitachi, users can adjust the radiation ranges to the colors. The 16.8-kg device can also detect three different materials, cesium-134, cesium-137 and iodine-131.

After the crippled Fukushima No. 1 nuclear plant tainted Fukushima and surrounding prefectures with fallout, municipalities have been struggling with decontamination work.

Hitachi's radiation gauge can help by visually indicating the progress made in decontamination efforts, the company said.

Hitachi said the device is its first that can visualize radiation levels.

Toshiba Corp. announced that it had developed a similar device back in December.

Toshiba's radiation measuring camera is more portable than Hitachi's, weighing in at 9.8 kg. It also indicates radiation levels by color.
