Japan is contributing 725,200$ (R9,468,501) towards a new initiative to use nuclear technology for the verification of the integrity of buildings following earthquakes and other natural disasters.

Following a natural disaster, specifically an earthquake, NDT can be used to determine hidden flaws in the structure, which can then be remediated quickly which will decrease short-term risks.

Industrial testing using nuclear technology involves the use of ionizing radiation (Among other methods) to test the quality of materials, without causing any or further damage to them, and leaving no radioactive residue.

NDT methods include radiography, a type of radiation technology, and gamma tomography, which is based on the differential absorption in different materials of gamma rays emitted from a radioactive source. Through the measurement of the rays that pass through the material without being absorbed, its make-up and structure can be identified. These techniques are able to identify structural defects that cannot be discovered through traditional testing methods.

The new activity will complement ongoing IAEA work under a technical cooperation project to support the preparation and recovery of civil infrastructures following natural disasters in Asia and the Pacific. Experts from countries in the region will be offered training and, when needed in the aftermath of a disaster, NDT equipment.
