Data processing primarily concerned with studying experimentally the distribution and excretion of inhaled mixed fission products, has been "streamlined" and automated considerably. An automatic read out counting system is in use which allows the radioactivity information from the scaling system to be transmitted directly to punch tape and/or type- writer. Additional sample information, such as tissue identification and weight, counting time, experiment number, etc., is preset with thumb- wheel switches into a data input box. Read out of the data input box just precedes scaler read out, the signal for which is given by the end of preset counting time. The punched-tape is converted to cards which are stored until completion of an experiment. At this time the information is used in a program to compute the necessary parameters for final distribution and excretion analysis. When desired, the computer plots the radioactivity data from any given series of tissue or whole body determinations and yields the constants of the least squares equations. Integration of the function may also be performed for dosage determination.
