Talk:Röntgen

From Wikipedia, the free encyclopedia

In the section on background radiation, I believe that there is an error in the conversion from R to mSv. The average lifetime dose is stated as 16 R or 160 mSv implying a conversion factor of 10mSv/R. This is close enough to the accepted value of 9.33 mGy/R to satisfy me. However, the range is quoted as 0.17 μR/h to 11 μR/h (1.5 to 100 mSv/a). Taking the first figure; 1.5 mSv/a = 1.5/10 = 150 mR/a = 150/365/24 = 17 μR/h. That is, a factor of 100 different from the stated value. The upper limit is out by a similar factor. The figures in SI units agree with the Wiki article on background radiation (average 2.4 mSv/a) and the Uranium Information Centre (http://www.uic.com.au/ral.htm) figures. I am therefore assuming it is the figures in Röntgen that are in error. I will make the appropriate edit to the main article. I hope no one objects. Spinningspark 17:01, 13 June 2007 (UTC)
