Description

Professional technologies for public radiation protection

Gamma detector POLISMART^® II PM1904 is designed for people who are at risk of radiation exposure in professional activities or in everyday life. The main purpose of PM1904 is to supply users with full and reliable information about accumulated individual radiation exposure and environmental radiation background in the real time.

Radiation detector PM1904 is a miniature gadget connected to iPhone® via dock-port. Detector control is performed by a smartphone with the help of App-application POLISMART^®, easy-to-use smart solution with convenient and user-friendly interface.

No special knowledge required.

POLISMART^® II users can also monitor radiation situation in various geographical regions. It comes from the possibility to integrate all POLISMART^® II devices into the unified geo information system. Each user is able not only to see his own radiation measurements but also to monitor the ones of other users who joined the System. All geo-linked measurements are displayed on the map.

Energy-compensated Geiger-Muller tube ensures accurate measuring of dose equivalent rate and dose from various gamma-radiation sources including ¹³⁷Сs, ²⁴¹Am,⁶⁰Co.

All radiation detectors undergo a comprehensive inspection of technical parameters as well as calibration via special metrology equipment.

Key functions

Dose Equivalent measurement in the range from 1 μSv to 10 Sv
Dose equivalent rate measurement in the range from 0.01 μSv/h to 13 mSv/h
Audio, vibro and light alarm of the DE/DER thresholds exceeding

Measurements are carried out within a wide energy range 0.06 – 1.33 MeV with accuracy of no more than 20 percent.

iPhone^®connection mode

Gamma-detector POLISMART^® II PM1904 can be connected to iPhone® with a dock connector.

Advanced iOS App POLISMART^® allows PM1904 to operate with a mobile device.

The App includes the following features:

Independent audio or vibration alarm of the preset DE/DER thresholds exceeding;
Display of Dose equivalent and Dose equivalent rate measurement results;
Display of Measurements results in various units (Sv, R);
Track recording with radiometric data display on the map;
Radiation environment reports;
History of measurements with automatic grouping and convenient display;
Flexible custom settings (thresholds, radiation units, data sorting, filtration and so on);
Network integration into the unified geo information system;
Display of geo-linked measurement results of other users;
Measurement results sharing via Twitter, Facebook.

The App is available on the iPhone^® App Store.

Autonomous operating

POLISMART^® II PM1904 can operate as a stand-alone device powered by built-in rechargeable battery.

In autonomous mode the gamma detector PM1904 continuously controls ambient Dose Equivalent (DE) and ambient Dose Equivalent Rate (DER) and records measurements (up to 500 values) in non-volatile memory. When preset thresholds are exceeded light alarm appears. Lifetime of the built-in rechargeable battery is no less than 500 h (in conditions of average values of radiation background).

POLISMART^® trademark has been registered to create a series of radiation detectors which can be connected to mobile devices via various interfaces. The first POLISMART^® modification appeared in 2004.

The product is protected by patent.

DASHBOARD

DOSE MODE

measures the Dose Equivalent, which is the total radiation energy absorbed by an individual. It also assesses the health risk of the radiation exposure to the individual.

DOSE RATE MODE

is intended for continuous measurement of gamma radiation intensity levels. If Dose Rate threshold is exceeded POLISMART^®II alarm sounds right away.

SEARCH MODE

enables detection and location of gamma-radiation sources. In Search modePOLISMART^®IImeasures radiation background level and compares it with the previous measurement.

Tap WayPoint button to save DoseDose Rate measurements with GPS coordinates into iPhone/iPad memory.

TRACK

The Track mode allows the user to track the movement of Radiation Detector POLISMART^®II and display it on the map. Track waypoints are added to the current track in accordance with predefined user conditions: Distance, Time, Radiation threshold exceeding.

1. START TRACKING

Having received GPS coordinates, tap «Records» to start recording your waypoint.

2. TRACKING

When the device is moved, the application automatically creates waypoints for a specific time period and distance.

3. SAVE TRACK

You can save the track name, date
and time.

SAVING BY TIME

Creates waypoints after specific time interval, specified by user.

SAVING HIGHEST VALUE

Creates a waypoint once the threshold is exceeded.

MANUAL SAVING

Tap a button to create a waypoint manually.

SAVING BY DISTANCE

Creates waypoints after specific distance, specified by user.

HISTORY

WAYPOINTS HISTORY

All saved data are organized as event Sets in chronological order.

Sets include daily statistics:

·Waypoints number per day;

·Minimum Dose Rate value per day;

·Maximum Dose Rate value per day;

·Dose accumulated per day;

Waypoints and Tracks can be sorted out by:

·Start and end dates;

·Time;

·Event name;

·Alarm event.

TRACKS HISTORY

is displayed in text, graph mode or on the map.
Share this information by
e-mail/Twitter/Facebook to inform people about environment background radiation.

WORLD MAP

This mode enables user to see waypoints on the electronic world map according to the set view track filter.

Users get access to the shared radiometric database for a particular area, city or even particular street.

WORLD SERVER

All POLISMART®II detectors can be networked to a unified geo information system.

Radiation measurements shared by other service members are uploaded to POLISMART^®II World Server. Through access to Polismart.net service, users can track radiation background levels in real-time worldwide.

SHARE INFORMATION

In one tap the measurment results can be shared via Email, Twitter or Facebook.

SETTINGS

The application allows the user to adjust hardware and software.
Most important, the user can set threshold levels by his own discretion.
The user can also choose Imperial or Meter distance measurement unit (a yard/mile or meter/kilometer).
Other options include Roentgen or Sievert measurement units.
POLISMART^®II application allows the user to set up Word Server function, tune the Alarm and Track setting, customize the dashboard and much more.
