Airliner encounters with radioactive bomb debris
I have a vague recollection that back in about 1961 there were instances of DC-7 Anchorage to Copenhagen polar flights (perhaps by SAS) that encountered radioactive bomb debris from Soviet atmospheric tests. Those aircraft, if I remember remember properly, required significant decontamination after those flights. I have been unable to find independent confirmation of my recollection and I wonder if PPuNers could help my memory
