The Atomic Energy Council (AEC) said Saturday that it conducts random checks on tiles sold locally every season and that there is no need for the public to worry about their safety. The AEC made the remarks one day after domestic tile manufacturers went to the legislature to call attention to claims that the government has been allowing substandard Chinese tiles to enter Taiwan via Vietnam and Indonesia. The Taiwan Ceramic Industries Association has estimated Taiwan's tile market to be worth about NT$25 billion a year, with tiles from China now accounting for 40 percent of the figure. Lin Chin-tsai, secretary-general of the association, also said the Chinese tiles are not examined, are uneven and break easily. He also claimed that they could have high radioactivity. However, the AEC pointed out that it conducts random checks on tiles every season and that they come from Taiwan, Turkey, Spain, Thailand, Italy, Vietnam and Indonesia, as well as various other countries. The test results show that the tiles fall within 0.07 mSv/h and 0.09 mSv/h, well within the tolerance level for radioactivity, so that there is no need for concern. 'The council will continue to conduct checks on tiles to ensure public safety,' the AEC said.
