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

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
versions, 1024 px.
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.
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).
The icon for this page is an atom drawn in the same manner. I think it scales down nicely.
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, diamond, or water. 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.
