In general, I like the plots, but I find it hard to get past some of the technical errors. For example, the terrorists protect themselves from Cesium 137 radiation using respirators. Also, the Cesium is "securely" stored in glass vials. Another faux pas is that the Cesium bomb is triggered remotely via cell phone. The bomb is located in a hospital where they are jamming cell signals. Therefore, the terrorist tries to get far enough away from the hospital so that his cell phone can work and can supposedly trigger the bomb. Only problem is that the receiving phone on the bomb is still located in the hospital where cell communications are jammed. I can normally overlook some reasonable technical errors, but these seem ridiculously blatant to me.
