Food radiation testing system developed by Fuji Electric

We don't know what are the exact consequences of consuming rice exposed to harmful levels of radiation, and we don't want to try. Fuji Electric has developed a high speed food radiation testing machine that scans bags of rice for the radioactive cesium levels. The machine has a conveyer best that takes the bags of food items under the set of scanners which detect the levels of radiation. For a typical 30 kilogram of rice bag, the machine only takes 10 seconds. It doesn't need any special training to operate the machine and testing is done while the food item is still inside the cardboard boxes.



The machine developed by Fuji Electric sets itself apart by not allowing the external radiations to affect the radiation measurements. The machine has a shadow shield that prevents the external cesium radion from affecting the sensors directly. In Fukushima, all the foot items are tested for radiation and current generation of machines can scan about 4-6 bags effectively. However, the scanning machines need to be a lot faster to save time in scanning. The food scanning machine from Fuji Electric tests the levels of cesium 134 and 137 in food items. The machine allows testing iodine 131 levels, depending upon settings. Fuji Electric plans to extend the capabilities of their machine to scan other food items as well. Currently the machines only scan rice.

The company has already delivered about 50 of these machines to Fukushima. We've a video of the machine in action, take a look -
