Production of Medical Radioisotopes with High Specific Activity in Photonuclear Reactions with $\gamma$ Beams of High Intensity and Large Brilliance

, 2010
We study the production of radioisotopes for nuclear medicine in $(\gamma,x{\rm n}+y{\rm p})$ photonuclear reactions or ($\gamma,\gamma'$) photoexcitation reactions with high flux [($10^{13}-10^{15}$)$\gamma$/s], small diameter $\sim (100 \, \mu$m$)^2 ...

Terrestrial radioisotopes in black shale hosted Mn-carbonate deposit Urkut, Hungary)

Terrestrial radioisotopes in black shale hosted Mn-carbonate deposit Urkut, Hungary)
Previously, little attention has been paid to terrestrial radioisotopes (U, Th, K-40) occurring in manganese ores, despite the fact that the biogeochemical relationship between Mn and U is versatile. Occurrence of terrestrial radioisotopes in great amounts during mining on a long-term causes significant radiation exposure.

Dielectrics for long term space exposure and spacecraft charging: A briefing [PDF]

Charging of dielectrics is a bulk, not a surface property. Radiation driven charge stops within the bulk and is not quickly conducted to the surface. Very large electric fields develop in the bulk due to this stopped charge. At space radiation levels, it
