MISAWA AIR BASE, Japan – Tech. Sgt. Vanessa Cifuentes, 673rd Aerospace Medicine Squadron, bioenvironmental technician, reads the display on a multi-purpose survey meter for radiation levels at Misawa Air Base April 29. The radiation levels displayed reflect the same readings Misawa Air Base has been receiving since the earthquake -- zero amounts of radiation above background levels found.
