"radiation monitoring equipment"

Pray tell of this equipment.

Dad used to bring home rocks from the cobalt fields in Ontario and a Geiger counter, get me to hide them in the house and he would find them. I was fascinated as a boy of four or so.

Dad and the lads used to have their film tags read every day before leaving the base (CFB Trenton). When they got close to the weekly limit, they would leave the the tags in their desks at the base before going to *****. Everyone who worked on his team died of cancer which began in the upper femurs. Nuclear warfare is dangerous business.
