Fukushima cleanup turns to muon tomography to map wreckage

New York Times : Parts of the Fukushima Daiichi nuclear complex are still too dangerous to enter after the tsunami-caused disaster three years ago, and the construction of the structure itself prevents the use of conventional imaging such as x-ray tomography. Toshiba, the company in charge of the cleanup, plans to hire Decision Sciences International to use muon tomography to create a picture of the wreckage prior to cleaning those areas. Muon tomography, which uses the scattering of cosmic ray muons to create three-dimensional images, has been around since the 1960s, but the level of detail it provides has only recently reached a point that makes it useful for the cleanup efforts.
