fallout contours การใช้

• Some agencies that promoted " evacuate immediately " guidance as a response to potentially lethal fallout arriving, advice which may have been influenced by these agencies assuming simplistic single wind driven cigar / Gaussian shaped fallout contours would be representative of reality, have since retracted this advice, as this can actually result in higher radiation exposures as it would put people outdoors and in harm s way when the radiation levels would be highest.
