 - Caveat!  
 I encourage you to distrust everything I say 
 (and everything anyone else says) 
 on this subject until you have seen (and believe) 
 the data for yourself.  Like most people, I am not 
 a scholar or even an expert in the field of radiation hazards, 
 just an amateur with strong convictions which will distort 
 my presentation of the evidence; my only excuse for 
 subjecting you to my opinions is that everyone else 
 seems to be so timid about expressing any ideas on this 
 subject that the only information you are likely to get 
 elsewhere (without determined effort on your part) 
 is even more politically motivated and less reliable than mine, 
 which I acquired through informal discussions with various 
 people who do have legitimate professional credentials.

 - Whether or not 
 genetic mutations are beneficial for the 
 human race as a whole is a difficult question both 
 scientifically and ethically; I will avoid trying to answer it.

 this is because of multiple redundancy or context programming 
 I do not know, but it sure is an impressive feat.

 - I should add an extra caveat 
 at this point: what I have said about single- and 
 double-strand breaks and healing times is what I recall 
 from sitting on the PhD committee of a student working 
 on pion radiotherapy about ten years ago.  I don't imagine 
 it has been substantially revised since then, but I am 
 not absolutely sure.  If you want a more reliable witness 
 I will be glad to direct you to local experts.

 -  . . .  idea.5
 - Even 
 if a sufficiently totalitarian regime 
 could be instituted to forcibly prevent the population 
 from increasing exponentially once immortality was 
 commonplace, would such a thing be beneficial?  
 Would life seem as precious if it were not so annoyingly 
 short?  Again I shall bypass the thorny issues 
 and play the hand I am dealt.

 surprisingly enough, from the radioactivity 
 released from fossil fuels in combustion, which is far 
 greater than that released by a nuclear power plant

 -  . . .  20.9
 - Actually, 
 the RBE of neutrons varies tremendously 
 for different tissues and is a complicated function 
 of the neutron energy because of the energy-dependence 
 of the neutron capture cross-sections of different elements.  
 Neutrons are very bad.

 -  . . .  stick.10
 - The purpose 
 of SI units is evidently to make it as difficult as possible 
 for intelligent laypersons to understand what ``experts'' 
 are talking about.  I cannot imagine a more humiliating 
 posthumous fate than to have countless generations confused 
 by some perfectly simple unit renamed the ``brewer'' 
 in honour of my efforts to make some field more understandable.

 medical X-rays are normally localized

 and therefore are not as bad as they look.  Still . . . .

 -  . . .  0.7 mR/h.12
 - Note: 
 that is per hour at a typical cruising 
 altitude for a normal commercial jetliner; thus an average 
 round-trip transcontinental flight yields a dose of 6-8 mR!   
 The estimated average cosmic-ray dose for airline crew 
 is 670 mR/y.  Astronauts have it even worse.

 but in the Okanagen, where there are concentrated 
 uranium ore deposits, I might choose to live 
 in a wooden house.  However, you should check out 
 the latest data before you jump to any conclusions.
