On page 164 of the 1970 Radiological Health Handbook is a very useful
graph entitled "Half-Value layers at Photon from 10 keV to 10 meV".
I was looking into electronic ways to interpolate values from the graph
but found that the only twp pieces of software that would allow me to
get absolute pixel coordinates from the image are Photo Shop or MatLab -
I have neither and can't afford either. (with the pixel coordinates of
the 4 corners of the plot and the point of interest - a spreadsheet that
would return the value of the point of interest would be a trivial
So - the question here is - does anyone have this plot in a better
quality electronic image, or has anyone worked out the data points from
which it was compiled or has anyone come up with or found an electronic
way to get this information?
