Radiation Dosimeter Comparison

Do I need an electronic dosimeter? Analog dosimeter? What is the best type of radiation dosimeter for my application? It is important to choose the correct nuclear radiation dosimeter if you’re on the job around potential exposure. The following chart will help you decide on the best one for your application. Customers can contact us if further consultation is needed. We’re always happy to assist.

The Pen Dosimeter is a nuclear radiation dosimeter with a gas filled chamber. A small meter filament inside the unit tracks your dose. No batteries are needed. Simply look through the pen to see your dose, much like a telescope. The Sentry EC is an energy compensated GM based dosimeter and rate meter. It had internal memory, USB, and is the most rugged of our line up. The solid aluminum enclosure comes with the belt clip attached. The RAD-60 is a pager style dosimeter with an LCD readout and Si diode based detector.
