[ RadSafe ] CT radiation INHIBITS cancer

[HOWARD.LONG at comcast.net]

True, Otto. Statistical "Significance" is arbitrarily 95% not by chance. 

However, bomb data is the only HUMAN "experiment" available for  

high rate, low dose radiation, like CT, except CTs themselves. 

All exposed more to than 10 rad showed  more cancer, 

so "all above 1. rad" averaged in those with damaging high dose. 



Have you heard about the statistician who drowned? 

He was crossing a creek that AVERAGED  one foot depth. 



Do you concede that the 34 breast cancer deaths 

suggest benefit MORE LIKELY than HARM, from radiation 1 to 10 rad 

 -- when 42.3 were expected without exposure? 



Best regards, 

Howard Long

THIS 32 VERSUS 42.3 IS NOT A STATISTICALLY SIGNIFICANT DIFFERENCE AND DOES NOT DISPROVE THE HYPOTHESIS THAT THERE IS SOME REAL RISK IN THIS RANGE. 

Overall the RERF found a highly significant 275 cases of breast cancer among atomic bomb survivors for exposures above 1 rad (p<0.001) with an excess relative risk near 1 per sievert (double risk at 100 rad).
