PEN Dosimeters PEN Dosimeters | PDF Flyer | English Manual |
The advanced PEN direct reading dosimeters are rugged, precision instruments. They are higher quality and have greater reliability than other dosimeters of this type. They measure and directly read, at any time, accumulated dose (quantity of gamma and x-ray exposure). PEN dosimeters are designed to satisfy military specifications for the RADIAC METER IM-264/PD and ANSI N 13.5 and N322 requirements. A sturdy metal clip attaches the dosimeter to a pocket or any object to monitor total radiation exposure. They are hermetically sealed and immersion proof.

PEN Dosimeters / How often do I have to recharge the Pen Dosimeters?

It all comes down to user preference. Technically, you can use up the whole range of the pen dosimeter and recharge it then. That would mean that a person would have to record the last reading after use and use that last reading as the zero when the use it again, tracking any changes between the two. However, the more common practice is to recharge them and bring the reading back to zero after each use.
