LACRITSENs Is it not also possible that raindrops could pick up ve snall particles if one or both are electrically charged dhe te static electricity? Doegthat cone into thia? ” SFLLOGs That is somthing that we certainly looked st. I was jusk going. to say that we went on, having decided that at least the Langux theory would not account for the saall particles, and we Felt thet one should certainly investigate all the possibilit tringing down the small particles — wa leave open for for th monent whether they are saall or not. The evidence seas to be that there are - for an air burst - @ great many enall perticles where there is no contact with the sand, L ITSENs KFLLOOGs Isn't it true the raindrops somtines are electrically ch That's right. Stan Greenfield locked into this in a good] dsal of detail, and observations in a normal cumulus cloud show 30 te LO - or so = primary charges on a cloud droplet in a cumults type cloud, soin a normal type cloud there is a charge. It cocurred to us that there might aleo be « charge on radioactive particles ~ due to the fact $hat they are emitting electrpans, those that are beta exitters, Well, we didn't get veryfbr this investigation before we discovered that the dominate is the suall ion content in the atmcsphere, and that where have racicactivity se have a very large production of small into factor we ions, well above the normal background which ocours froa cosaiq reys and naturwl radicactivity in the wir, Therefore, the droplets Derartrmont cf mre] Historians 7. 23 ARCiiivcS
