[ RadSafe ] Encounter with Caldicott and Gundersen on KGO Radio

[Hans Wiegert]

We learned about "skyshine" the hard way. In 1956 we started 1.5 MeV
electron beam accelerator in a "Blockhouse". While the walls were thick
enough to provide adequate shielding, the roof was not and radiation was
scattered back down.

Live and learn!
