The fact that mostof t lost weight may indicate that they receiv dose of radiation sufficient to interfere with imal metabolism. In spite of their relativel, active life and hearty appetites many of adults also lost weight which may indicates interference with their normal metabo!

It would appear that a higher percentage of the individuals in Groups I and II developed upper respiratory infections com- pared to Group [V. However,all of the indi- viduals in Groups I and II were questioned concerning even mild symptoms of URI, whereas only those of Group IV with severe symptoms of URI cameto theclinic. 2.6 Changes in Weight as an Indication of Disturbance in the General Metabolism Tue Bopy Wercur of individuals in Groups I and IT was followed routinely.
