This publication by IAEA is a good summary of considerations relating to control rod (CR or RCCA) material selection and lifetime management. I was wondering today, how long boron control rods remains in a nuclear power plant? As low as 4 years, as high as 30 years. Depends on the CR location in the core, since power varies with radial distance from the ...

The difficulty with this sort of device is that the effective cross section of the target nuclei are so tiny. Even with a very dense target, most of your shots will miss. But you still have to consume energy to send them along. The most important thing for efficiency then is nuclei density in the target. Making the target full of negative ions isn't ...

XKCD Radiation chart puts everything in perspective. 1 banana to 1 hour near Fukushima. If you're a beginner in the field, think of contamination(and other radioactive stuff) as the poo and radiation as the stink. You mentioned they weren't wearing suits. The suits are only used for preventing personnel contamination and have little impact of exposure. So ...

"Zero background radiation" - is the natural expected radiation measured far away of the specific pollutant site - the coal mine. It is a control or reference value in the study. ...
