• Automatic cumulative dose & ID readout, into data base
• Facilitates configuration of alarm settings and dose calibration
• Data storage automatically after each readout q Dose records data base gives weekly, monthly, & yearly cut dose of individuals.

IR Docking Station DS713 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 DS713 is designed for docking PD714, 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.

FULLY-AUTOMATIC TLD BADGE READER [type : TL1010]

Technical Data

Fully Automatic TLD Badge Reader TL1010 is a personal monitoring system, designed to read the TLD card (TL dosimeters) worn by radiation workers.
This Badge Reader system is designed using state of art electronics, electro mechanical system, embedded code and software to load and read the TLD cards for TL glow curve / dose.
This Fully Automatic TLD Badge Reader is provided with an extra facility of sensing the unique ID of TLD Cards.
System facilitates storing of dose record and glow curve. TL dosimeter is heated by hot gas (N2) jet to 280oC and TL output is recorded using PMT whose integral of the current output is proportional to the dose.
It is a Thermoluminescent dosimeter based personnel monitoring system. Thermoluminescent dosimeters make use of the property of certain materials which absorb energy when exposed to X, Gamma or Beta radiation. On heating, the absorbed energy is released in the form of visible light. A plot of light intensity emitted against temperature is known as a glow curve. For a given heating rate, the temperature at which the maximum light emission occurs, is called the glow-peak temperature and it is characteristic, of the individual TL material (also called phosphor).
The quantity of the visible light emitted (TL output) is found to be proportional to the energy absorbed by the TL material. The estimation of radiation exposure may be based either on the height of the glow curve (differential method) or the area under the glow curve (integral method).
The TLD personnel monitoring system essentially consists of two major parts: TLD badge and the TLD badge reader.
The TLD Badge comprises of a plastic cassette containing three Teflon TLD discs (13.3mm and 0.8mm thick) that are mechanically clipped on to circular holes (12.0mm) punched in an aluminium card (52 x 30 x 1mm).
The TLD Badge Reader is designed to measure X, Gamma and Beta radiation dose. The metal filter combination (1mm Al + 0.9mm Cu) is provided to reduce the photon energy dependence of the TL discs. The TL badge reader is calibrated such that the TL output of the disc under the metallic filter reads directly the gamma radiation dose.

Motorised driver assembly for automatic feeding of 50 dosimeter cards loaded in a magazine. Software IBM PC compatible menu driven in WINDOWS based software for transfer of data to user defined file, storage and display of glow curves, computations of dose and generation of dose reports.

Temperature Monitoring Chromel Alumel thermocouple in hot gas stream. External temperature monitoring output at the back panel. Range Selection Automatic from 9.999µSv to 5.000Sv Calibration Coarse adjustment by varying the EHT through a potentiometer in the EHT circuit; fine through software. Safeguards Heater/Gas flow failure.: The heater and gas flow are checked for failure in every dosimeter readout cycle. In the event of failure of heater or gas flow the readout is terminated and a message indicating heater / gas flow failure is flashed on the PC monitor. Mechanical Failure : Any mechanical failure during readout cycle is sensed using a timeout watchdog programme and the cycle is terminated with an option for the user to restart the cycle. EHT or the input circuit (I-F converter) is sensed and reading cycle is terminated in case of failure. Nominal Power Supply Power supply : 230V, 50Hz : Power requirements : 500 VA (max including PC) PC Requirements IBM Pentium IV or upward compatible, with FDD and HDD drives, VGA monitor, Serial and parallel ports with Windows XP operating system. Applications Personnel Monitoring of radiation workers in Nuclear power stations, Isotope laboratories, Industrial radigraphy installations, diagnostic & therapeutic radiology centres, etc.
