Radiochemistry


This page is intended to provide infor­ma­tion for labora­tory per­sonnel, especially radiochemists.

Note: If you want to down­load any of Keith’s confer­ence presen­ta­tions, click on Conferences above.

A few of the subjects:

  • The Multi-Agency Radiological Laboratory Analytical Protocols manual, including errata
  • Laboratory subsampling: Bias and variance
  • Radioactive decay and ingrowth
  • Measurement uncertainty? Maybe more on that subject some day.

Images

In January 2014 I tried my hand at ray-tracing some stylized images of atoms of the type often used to suggest radio­nuclides or nuclear energy. Below are some of the results in PNG format, free for down­load and use if you want them. Each ver­sion is pro­vided in three or four sizes: 128 px, 256 px, 512 px, and for the panoramic versions, 1024 px.

Radioactive

All these PNG images have trans­parent back­grounds, but the ones with a glow­ing nucleus should be dis­played only with a dark back­ground, as you see above.

Panoramic

The background scenery for each of the follow­ing images is a spherical pano­rama. (See the example at 360facil.com/eng.index.php.)

The last image above is the first one I made using a pano­rama of my own, which I built from photos taken of the count room at my lab. The pano­rama isn’t perfect, but it’s just a first attempt. Click here for a stereo­gram of the same model (and cross your eyes).

And finally here are several icons that I created to repre­sent alpha par­ticles, again using the pano­ramic photo of the NAREL count room. In all the variants, protons are shown as red or blue metal, with vary­ing levels of gloss­iness, and neutrons are shown as red, blue, or silver metal, or as clear glass or diamond. The image sizes in each icon range from 16 px to 256 px. The images used for the links them­selves are 128 × 128 PNG files, which might be use­ful as clip art.
