Simplicity and efficasity
In order to improve the detection limits in radioactivity measurements, the background noise should be reduced as much as possible. NPO has developed passive shielding made of lead for smear measurements (for example)
Easy to transport
This small compact solution replaces larger heavier lead brick caves to reduce background when surveying surface smears and other samples. The standard size (shown below) has 1” of lead on the top and bottom and 3” of lead on the sides and back. Caves are built to order and can be designed to suit your background reduction requirements. Finish is stainless steel. Handles are included.
