I am sure until I brought the subject up, most of you were unaware that moon dust was a health hazard due to it's radioactive alpha particle content. I am sure most of you were unaware that the surface of the moon was so radioactive that the radiation from the surface of the moon raises the background radiation in lunar orbit by 30 to 40%. Now do I need to inform everyone that radiation from a plane source diminishes as a function of distance, so that it is reasonable to assume the surface radiation is greater than the radiation reflected back into lunar orbit. Let us discuss the implication of these facts.
