Ambient dosimeter for use in extreme environments.
The PM1605BT electronic dosimeter is equipped with a Geiger-Mueller counter for extended measurement of the ambient dose equivalent and ambient dose equivalent rate. Instruments can search, detect, and locate radioactive sources, alert the user with audible, visual, and vibration alarms, and transmit stored data to a PC or smartphone.
The dosimeter is designed to withstand extreme environmental conditions such as limited visibility, raised noise, high temperatures, exposure to seawater, shock, and falls. Its control panel with two big buttons allows using protective gloves while operating the instrument.
The instruments are recommended for personal radiation protection of first responders, HAZMAT teams, civil defense, firefighters, and the other divisions that deal with radiological emergencies.

Operation principle
The PM1605BT ambient dosimeter continuously controls the dose and dose rate threshold levels and alerts the user with audible, visual, and vibration alarms when any of them are exceeded. The instruments can search, detect, and locate radioactive sources.
The instrument is supplied with the user software for downloading measurement history to a PC, maintaining the personnel exposure database, and adjusting the settings of the dosimeter. The PM1605BT is compatible with the Polismart® Android app via Bluetooth, which allows the user to monitor the instrument readings in real-time, download and transfer the history, and adjust the instrument settings.
