Radiation protection videos
During 2008 to 2010 Ionactive commissioned a number of radiation protection videos produced by Dr Chris Robbins of Grallator. The video resource covers radiation detectors (GM tubes), gamma ray constants, linear accelerators, radiotherapy treatment rooms, industrial radiography enclosures, radiation dose units, inverse square law, radiation (photon) scattering, CBRN (radiological and nuclear hazards including the Louis Slotin criticality incident) and more.
These were put up on YouTube at a video quality which matched expectation of that time - and did well with plenty of views and comments (they are still there if you go looking). We have used the higher quality source files to represent these videos again, direct on the Ionactive website. We have improved and balanced the audio, and they now stream from Vimeo with no adverts. These videos are over 10 years old but the content stands the test of time - they are excellent radiation safety training resource.

The Gamma Ray Constant (Video)

Read moreAn Ionactive video release created for us by Grallator in 2009. This video looks at the Gamma Ray constant of the form D=ME/6r2 (terms explained in the video page). Later more recent resource (i.e. 2024) takes the concepts in this video and develops them much further - looking at the detailed maths and physics (links will be found on the video page). There is still lots of good radiation protection educational content here despite its vintage.

This revolution, the information revolution, is a revolution of free energy as well, but another kind: free intellectual energy.
