The effect of the radioactive fission products depends entirely on the distance to which they are carried by the wind. If 1 kg of fission products is distributed uniformly over an area of about 100 square miles, the radioactivity during the first day will represent a lethal dose (=500 R units): after a few days, only about 10 R units per day are emitted, If the material is more widely distributed by the wind, the effects of the radioactivity will be relatively minor.
On the first objective and still under continual enemy fire, Major Anderson re-organised the Battalion and rallied men whose Commanders, in most cases, had been either killed or wounded. The Commanding Officer having been killed, he took command of the Battalion and led the assault on the second objective. During this assault he received a leg wound, but in spite of this he carried on and finally captured ” Longstop ” Hill with a total force of only four officers and less than forty other ranks.
