Regarding Tai Kawabata's March 25 article, " Reveal fallout data": Radiation detectors need to be set up in concentric circles around the Fukushima nuclear plant and results posted periodically on the Web. Air monitoring sensors like those at the University of California at Berkeley — go to www.nuc.berkeley.edu/UCBAirSampling — are recommended. These should be established with instruments providing instantaneous real-time values.
