The situation at WIPP is unstable, another large underground radiological upset occurred on March 13th. WIPP has NOT publicly acknowledged this most recent event, but its existence is documented in readings taken from mine exhaust air at Station A. That data shows a 1000% increase in radiation on 3/13/14; with a reported Alpha radiation reading of 368 Disintegrations Per Minute [DPM] and 57 DPM's of Beta radiation. Post HEPA filter Station B readings have NOT been made available.
The magnitude of the March 13th radiological spike is on par with readings taken nearly a month ago on February 17th roughly 3 days after the initial explosion. The risk of larger follow-on explosions at WIPP can NOT be ruled out. We expect the follow-on risk of explosion will increase during mine re-entry, as that activity may ignite explosive gases generated by the nuclear waste.
