    Not an average software engineer--beautiful page (imperfect spelling)! Why does detection scale as the 4th root of the RCS? Nice problem for the radiation theory part of a graduate…

    This appears to be prodigiously powerful, but has a --dry-run option and support for whitelists. I love the fact that it's a lightweight and verbose script.

    Depending on the field, 3 Gy IS 'small' (with respect to doses to tissue during cancer treatment, which can be 60 Gy). Whole body doses of 1 milliGy in the environmental biz are co…

    I like this very much. BUT: What I cannot save I do not remember (quoth the Old Guy). Any way to save these images as SVG. (Screen grabs are less satisfactory.)

    I welcome the new library! I have used a RadiaCode 103g for more than a month. I also have a more conventional NaI:Tl 5cmX5cm scintillator+PMT in my basement with 95 lbs of lead sh…

    As noted, ordinary maps may suffer (for example, in epidemiology)from the impact of a very non-uniform population density. A disease cluster then MAY be a cluster, or it may be ord…

    I've used XRG (free) from gaucho.software through many changes of hardware CPU numbers and macOS versions. Light and fluffy, for me at least.
