Digital Pocket Dosimeter – II

Digital Pocket Dosimeter – II [ TYPE : PD 716 ]

Technical Data

Digital Pocket Dosimeter Type PD716 uses Si-diode as the radiation detector. This serves as personnel radiation monitor with alarm to cater to the needs of radiation workers in Nuclear installations, Reprocessing plants, Radiochemical plants, etc. It also finds use in medical, industrial, other applications where radioactive isotopes are used for a variety of applications.

It measures integrated radiation dose in the range of 1µSv to 99.99mSv and doserate in the range of 00.1µSv/h to 99.99 mSv/h. It is also provided with preset alarm feature for generation of audio alarms in the event of high dose / doserate. The user interface to the instrument is through the LCD display and a single push button switch. The dosimeter is provided with an optical port for data communication with PC for the purpose of setting preset alarm levels and for calibration of the dosimeter.

Its design is based on nano watt technology resulting in a battery life of better than 2000 Hrs of continuous use.

Additional options :
i. Docking station for PD716 .
ii. Dose records data management software DS717.

Software :

IR Docking Station DS717 under the control of the PC communication software, primarily facilitates automatic readout of Cumulative Dose along with the Unique ID apart from configuration/calibration of the dosimeter. The Docking station communicates with the Dosimeter through IR port at a baud-rate of 1200. On the PC side it gets connected through the USB port. This Docking station DS717 is designed for docking PD717, derives power through the USB port.

Dose records data management software (DRMS) is designed to read total dose from the dosimeter automatically once the dosimeter is placed on the docking station. It also facilitates Configuration of Alarm Settings for Cumulative Dose and Dose-rate, assigning Unique ID for individual dosimeters, Calibration of the dosimeters for Cumulative Dose. The Application software routes data to Dosimeter through virtual comm. port to Docking station which in turn routes the data through IR port to the Dosimeter. Once the data is retrieved into PC, it gets recorded in a database. Users can retrieve and analyze data – ID-wise, Day-wise, Month-wise, Week-wise.
