The Apex OSL Badge is small, lightweight and rugged Beryllium Oxide (BeO) Optically Stimulated Luminescence (OSL) based dosimeter. It is highly sensitive to X-rays and higher energy Beta particles. If there are questionable readings, this dosimeter can be read multiple times to ensure accuracy. The Apex is ideally suited for a wide range of applications and environments.
CHP Dosimetry offers several different dosimeter options, including whole body, ring, wrist, and Instadose dosimeters. While CHP recommends quarterly monitoring services, we will be happy to accommodate your needs if we can. Read more about the Apex dosimeter below where you can also place an order and pay online. Convenient!
