AN abandoned military training camp has been refurbished as the territory's only radiation shelter to house residents and tourists on remote Ping Chau in the event of a disaster at Daya Bay power station, 12 kilometres away. But both the island's elderly residents denied being told about the shelter or what they should do if radioactive debris began to fall. 'There is nowhere to hide if an accident happened. The only thing I can do is sit here and wait to die,' Lee Wing-wah, 69, said. Ping Chau police seemed unsure of what they should do in an emergency or even what was inside their radiation protection packs, thought to contain masks. 'I think we would bring the people to the abandoned houses in the village or the military camp. But I don't know exactly where we should go,' a constable said. The police post possessed emergency signs to warn people about radiation. The post contained iodate pills which prevent the intake of radioactive iodine. Security Branch officials admit the camp buildings have not been built as radiation-proof facilities and are not airtight, as recommended by a nuclear expert. Five former military buildings on the island - the only Hong Kong land within the Government's 20-kilometre evacuation zone of Daya Bay - were modified as a radiation shelter last year in case the police did not have time to remove people from the island before the radioactive cloud passed over. Radiation could reach the island within an hour of a major disaster, experts have estimated. Assistant Secretary for Security Christopher Leung Sheung-lan said the shelter could hold up to 1,000 people. Hundreds of picnickers flock to the island at weekends and holidays. People would only be evacuated when the radiation fell to a safe level. Air conditioners and iron window covers had been installed in the brick houses to prevent people breathing contaminated air. But there were no airtight or special facilities to provide maximum protection. 'We believe that it is impossible to have a disaster like the Chernobyl explosion because of the reactor's advanced design. 'So, we would not take such a disastrous situation into consideration,' Mr Leung said. 'What we expect is to only keep the people in the houses for a maximum of a few hours before evacuation, even if we have to take emergency action.' However, the University of Hong Kong nuclear engineer Dr Raymond Yeung Man-kit has said that people throughout the territory can increase protection against cancer a hundred-fold by staying indoors and making facilities airtight. Dr Yeung has said people should close and tape all windows, turn off the air conditioners and even leave shoes outside if they became contaminated by ground-level radiation. The effects even of the small doses of radiation that could affect Hong Kong were unknown and should be avoided, he said.
