Abstract:
We designed a compact and portable laser radioactive decontamination system using a passive Q-switched fiber laser and a polygon scanner. The passive Q-switched fiber laser produced average power of 15 W at a repetition rate of 60 kHz. The scanner system contained a 12-sided spinning polygon mirror driven by a DC motor. By varying the spinning speed of the polygon mirror, we achieved a processing speed of up to 88,500 mm/s. This system was demonstrated to be very efficient for radioactive decontamination on surfaces of various metals: stainless steel, brass, iron, and aluminum.

Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
