Re: beta particle range



Bob Dunn,

	Cember's Introduction to Health Physics lists the following equations:

R= 412 E ^(1.265-0.0954 lnE)
  for 0.01 <= E <= 2.5 MeV

ln E = 6.63-3.2376(10.2146-ln R)^1/2
  for R <= 1200

R = 530E-106
  for E > 2.5 MeV, R > 1200

where R = range, mg/cm^2
         E = maximum beta-ray energy, MeV

Hope this helps and you have not gotten 8 million responses
