A nuclear explosion occurred near the epicenter of the Chinese earthquake, according to the Epoch Times. Overseas Chinese website Boxun News reported that the expert confirmed there was a nuclear explosion near the epicenter, based on witness reports and the discovery of concrete rubble believed to have come from an underground military installation.
According to a China News Services (CNS) report on May 31, 2008, paramedics from People's Liberation Army (PLA) hospitals and psychologists from Beijing onsite May 23 found concrete debris at the bottom of a valley near the epicenter. The half-mile-wide valley was covered with debris 10 — 20 inches thick, covering the valley floor for almost 1.5 miles.
Chinese Internet surfers commented that right after the quake military Special Forces blocked traffic heading toward the epicenter on the mountain, and men in white chemical protective clothing in military vehicles were also spotted driving toward the mountain. Rescue personnel near the epicenter were all military, according to witnesses.
The expert believes the nuclear explosion was not confined to the underground test area and has caused radiation contamination, stating that in a call to Beijing he recommended authorities accept help from other countries, seal the area, find and provide help to those who had been exposed to contamination during the rescue work, and take emergency measures to prevent water contamination."
