Safety Computer Forecasts Atomic Fall-out Pattern (May, 1956)

Safety Computer Forecasts Atomic Fall-out Pattern

How “safe” is it to test an atom bomb ? Will wind-blown radioactive dust or charged rain clouds endanger life or crops in inhabited regions?

The National Bureau of Standards recently developed a “portable” analog computer to assist in predicting radioactive fall-out from a nuclear explosion. The fall-out pattern appears instantly on oscilloscope (left of photo) after weather data and the size and type of bomb are “told to” the computer by setting dials. As computers go, “portable” means that it will fit into a truck.

Wind-carried fall-out even from “small” atomic tests has traveled as far as Paris and Tokyo when caught in the “jet stream” of the upper atmosphere.

    A computer that fits inside a truck?

    Nah, it’ll never happen.

    Apparently the “author” didn’t believe in the “words” he used having the “meaning” people would usually “assume.” As reporters go, “author” means the person responsible.

    Destroy trojan and create a better impression.
    Being a MCS student much of my study work is dependent on computer but the computers of our MCS department were always plagued with trojan, as a result of which the speed of our computers drastically decreased. Our professors were also tensed as the syllabus was not getting completed in time due to which we students were also loosing interest in studies. Then I learnt about search-and-destroy. I told about it to my professors who decided to go for it. Within a few minutes all the Trojans were destroyed, the results………my professors were highly impressed by my suggestion.
