DIY storage boxes
Building on an earlier post about DIY storage, and very much proof of concept. Two boxes for NORM storage, 12” x 6” x 3” and 14”x 9.5” x 3.5”
3/4” wood used to frame the sides and bottom with a 1/3” piece of plywood for the lid. 1/8” inch lead sheet next, wrapped in aluminum foil tape. 1/8” plywood is next with three to four layers of copper foil tape on the outside to mitigate Bremsstrahlung.
A pice of 1/8” lead sheet will be affixed to the lid with ideally a 1/4” acrylic block cup to the final opening.
NORM specimens as follows:
Threadgoldite - 15K cpm
Uranosilite: 525 cpm
Chernikovite: 3,400 cpm
Strelkinite: 180 cpm
Autunite: 180,000 cpm
Curienite: 54,000 cpm
Sklowdowskite: 45,000 cpm
At roughly 30” distance my GQ GMC-600 records negligible over background radiation in the larger box, moved to smaller box.
Any and all questions and suggestions are welcome!
