Portable Dosimeter TN-RD-90

MOSFET DosimetryPortable Dosimeter TN-RD-90The Portable Dosimeter, model TN-RD-90, is an economical,compact, stand-alone system for radiation dosemeasurement.Patient dosimetry measurements are available at the touch ofa button and display on the integrated LCD, without the needfor software or a computer. Additionally, the rechargeablebattery powered dosimeter allows easy transportation fromroom-to-room, or hospital-to-hospital.The Portable Dosimeter supports up to two simultaneousdose points with any of the Best Medical Canada singleMOSFETs on standard or high bias setting for optimaldose reproducibility. An automatic mode is available tocontinuously sample dose data at a fixed time intervalduring a session.After every measurement the dosimetry data is automaticallystored to memory for later viewing and can be downloadedto a computer via a USB connection and the PortableDoseConnect software. A simple, menu driven interface allowscustomization of calibration factors, dose units andoperational settings directly on the Portable Dosimeter.To save you time, a library of default calibration factors isstored in the memory, but the user also has the choice ofentering their customized calibration factors.Radiotherapy clinics can utilize the Portable Dosimeter forpatient dose QA, or to measure exposures to regions-atrisk.In diagnostic radiology, the system is ideal for residualexposure dose measurements, and protocol evaluation.For one-to-two dose points, the Portable dosimeter is a fast,simple solution for patient dosimetry that can be used for awide range of applications in radiotherapy and radiology.Features:Stand-alone reader with LCDPortable and compactQuick set-up timeSimple menu operationSupports two MOSFET dosimetersSupports all single Best Medical Canada MOSFETsOptional data export via USB and PortableDose ConnectsoftwareCalibration factor libraryLong rechargeable battery lifeManual measurement mode, or Automatic Sequential modeNo software or computer necessaryApplications:RadiotherapyIn vivo dose – photon or electronSkin entrance and exit dose (TBI)D maxdose measurementsIMRT and TomotherapyBrachytherapyRadiologyPediatric CT doseFluoroscopy doseTN #102086.03413 March Road, Ottawa, ON K2K 0E4 www.mosfet.ca 1-877-668-6636
