FLUKE 35040 ADVANCED THERAPY DOSIMETER S/N:0000099750 35040 Advanced Therapy Dosimeter Introduction The Model 35040 Advanced Therapy Dosimeter (ATD) is a reference grade instrument used to measure the charge and current from ion chambers in Radiation Therapy, and provides bias voltage for all commonly used chambers. The ATD large clear display offers direct readings of charge, current, time, and radiation units over a wide range. The user can customize the display for basic use or for specialized applications such as brachy therapy. The Advanced Therapy Dosimeter exceeds the recommendations of calibration laboratories for leakage, linearity, and stability by a wide margin. This instrument raises the standard of Radiation Therapy measurements. Now with Timer Function and wider dynamic range Ultra long-term stability error of approximately 0.1% per fi ve years Virtually removes effects of system leakage during measurement. Uncorrected leakage < 10 fA over temperature range Eleven user-defi ned bias settings from - 500 to + 500 V Read out in C, A, R, Gy, Sv, Bq and more Applications Radiation Therapy requires great accuracy in the measurement of dose and dose rate values associated with linear accelerators and radioactive sources. The Model 35040 Advanced Therapy Dosimeter provides the long-term stability and accuracy demanded for calibrations, quality assurance programs, and protocols in Radiation Therapy. A unique electrometer design provides more accuracy than high meg resistor or capacitor feedback electrometers. The Advanced Therapy Dosimeter is fully stable within five minutes, a fraction of the time of conventional dosimeters. The flexibility of the instrument optimizes user efficiency and saves time. In battery operation or using AC Line, the ATD measures dose and effective exposure time in a single exposure, thus eliminating the need for multiple exposures for Co and brachy therapy measurements. Front panel controls select ion chamber calibration factors, facilitate entry of temperature and pressure values for air density correction, allow bias voltage selection, threshold level, timer control, and choice of display screens. The user-customized display screens can simultaneously show dose, exposure time, dose rate, effective exposure time, average current/rate, accumulated charge/dose, bias voltage, leakage, and other important information that ensures the validity of the instrument. The customization software allows design of 16 screens that display conditions, parameters, values and text. Up to 32 chamber factors, 11 bias voltages can be programmed. It is PC compatible and connects via a RS-232 cable. The sale of this item may be subject to regulation by the U.S. Food and Drug Administration and state and local regulatory agencies.
