[ RadSafe ] Skyshine

[Lantzelot]

Helbig hörde ett radioprogram med Gundersen (jag lyssnar just nu på det) 
och berättade om det på RADSAFE. Helbig hade inte hört talas om skyshine 
förut, men det tycks som om Gundersen använder ordet/fenomenet för att 
skrämmas.
Hursomhelst så har flera kommenterat och berättat om skyshine, mailet 
nedan har en länk till en artikel som tar upp fenomenet rätt grundligt.

Jag tipsade Helbig om Kallie Metzger, så han har spritt det till RADSAFE.

Om man vill höra Gundersen så finns instruktioner längst ned i Helbigs mail.

We take care with our collomated (Cs 137 - 662 keV) GR sources (used for downhole density measurements in oil wells) that when manipulating them on surface they are not pointed towards the drill pipe that is stacked in the rig, as this will appreciably increase the dose to our operators due to back-scatter. But the reflection from the atmosphere at this energy level is not appreciable: it requires a dense material (or much higher photon energy levels, as in an accelerator) for the back-scattering to be appreciable.
