  • INTRODUCTION
    The Ludlum Model 9DP, pressurized ion chamber meter, provides highly sensitive measurements of exposure and exposure rate. It can simultaneously display the exposure rate, integrated value and highest rate seen by the instrument. The integrated value can be reset (if desired) using one of the four convenient front panel mounted buttons. The stunning 256 color, bit-mapped display provides an optimized presentation of the data and is accompanied with icons informing the user of the active functions and instrument status. All logged data are written in csv format to a plugged-in industry standard USB thumb drive for convenient retrieval by a PC spreadsheet or database program. Alarms are manifested using color changes on the display and an acknowledgeable audio output.

    The 9DP is part of Ludlum's new Dimension series of meters employing state-f-the-art technologies that deliver enhanced performance, convenient connectivity and are easy to use. Instrument users have access to personal preference type settings via a free Dimension PC Interface program. Ludlum also sells a more powerful version of the Dimension Interface Program which additionally, sets administrator parameters and performs calibration. The Dimension series offers a modern measurement and display system that is very user-friendly, powerful and links tightly with PC's.

    The Model 9DP can be used for a variety of medical and health physics applications and is ideal for measuring exposure rates from leakage and scatter radiation around diagnostic and therapeutic x-ray rooms. The unit is shipped calibrated and ready for use upon arrival at the customer's site.

    The Model 451P state-of-the-art ion chamber survey meter is a hand-held battery operated unit designed for use in both rugged and normal environments. The Model 451P features a pressurized ionization chamber, providing enhanced sensitivity and improving energy response to measure gamma and x-ray radiation. The Model 451P employs microprocessor and LCD technology. The ergonimic handle features a large diameter cushioned grip and is designed to reduce fatigue associated with extended use. The case is constructed of lightweight, high strength materials and is sealed against moisture. Please specify at the time of order if you would like standard units (R) or SI Units (Sv).

    The display features an analog bar graph, 2.5 digit digital readout, low battery and freeze mode indicators. User controls consist of an ON/OFF button and a MODE button. The unit is auto-zeroing and auto-ranging. The display features circuitry that automatically activates the backlight in low ambient light conditions.

    The RS-232 interface can be connected directly to a computer for use with the Excel add-in for Windows, enhancing the functionality of the instrument. The software allows for data retrieval, user parameter selection and provides a virtual instrument display with audible (requires sound card) and visual alarm indication. The software may be customized by the user for specific applications.

    Applications
    The Model 451P is used in a wide range of medical and health physics applications. The Model 451P was designed to measure leakage and scatter around diagnostic x-ray and radiation therapy suites. Also, the Model 451P is ideal for site surveys and is regularly used by x-ray manufacturers, government agencies, state inspectors, research labs, biomedical technicians, and in airports for baggage inspection equipment maintenance.

  • Introduction...
    The 451 Assistant for Excel is an Excel Add-in, a program that adds optional commands and features to Microsoft® Excel. The 451 Assistant provides remote control for many of the 451 functions, real-time data logging with user defined alarm parameters and a real time virtual instrument display. The 451 Assistant automatically loads with Excel once it is installed.

    The 451 Assistant data logging function automatically records real time measured data in an active Excel worksheet. Each measurement in the data log is automatically placed in the active worksheet cell, then the active cell moves down to the next row of cells where it will place the next set of measured data. Each recorded measurement is time and date stamped. The 451 Assistant provides user configurable audible and visual alarms for the real time logged data. The picture and data shows radiation levels above the preset alarm in red, the blue data represents the radiation level below the alarm






    that has not been acknowledged. The black data shows when the alarm was acknowledged. See Control Options for more details.

    The 451 Assistant for Excel allows the user to configure the 451's internal data logging and alarm settings. It may also be used to download the 451's internal data log and saves it in an Excel worksheet where it can be easily graphed for quick trend analysis.

    The 451 Assistant provides automatic timed integrated dose measurement over a user defined integration period or user controlled integrated dose measurement. After the integration timer has expired or the user has stopped integration, the 451 Assistant retrieves the integrated dose from the 451 and inserts the integrated dose in the active worksheet cell and the average dose rate is placed in the next cell to the right.

    Applications
    This Model 451EXL information management software program is ideal for the facility Radiation Safety Officer or anyone responsible for maintaining a permanent record of spills and accidents for adjerence to state and NRC requirements. The remote control of the 451 series of Ion Chambers may be accessed by any computer on your facility network providing remote information management.

    Controls
    The 451 Assistant menu and toolbar provide an interface for the user to remotely control the 451, configure the 451, download the 451's internal data log and start / stop real time data logging and integrated dose measurements

    Connect / Disconnect Connects or disconnects the 451 to the computer's communication port
    Start / Stop Starts and stops computer data logging. When data logging is started, logged data is placed in the active Excel worksheet and the worksheet is protected to provide data security
    Logging Properties Allows the user specify computer data logging parameters. The data logging sample interval (2 seconds to 999 hours), total data logging period (2 seconds to 49 days) and computer date log alarms may be specified


    through this menu. These parameters are independent of the 451's internal data logging functions
    Integrate... Allows the user to select timed integrated dose measurement or user controlled integrated dose measurement. The user may also specify the integration period for timed integration from 1 minute to 999 hours. When timed integrate mode is selected, the 451 Assistant for Excel stops the integrated dose measurement after the specified integration period has expired.

    When timed integrate mode is not selected, the user controls the integration period and the integration time is displayed in real time. The integrated dose and average dose rate are recorded in the active Excel worksheet when integration is complete
    Download Log The 451 is capable of internally logging data at a user defined interval from 1 to 255 seconds with a total capacity of up to 2700 data points. This feature allows the user to download the 451's internal data log into the active Excel worksheet
    Options Allows the user to change many properties of the 451 Assistant for Excel and several of the 451's properties. The user may configure the various visual and audio alarm features of the 451 Assistant for Excel for each data point that is logged. The 451 Assistant can be configured to use 2 or 4 alarm states. The four alarm states are acknowledged normal (below alarm level), unacknowledged normal, acknowledged alarm and unacknowledged alarm. The user may also select the communication port used by the 451 (default is COMI). The 451's internal data logging parameters and alarm settings may also be changed from the Options menu

    System requirements
  • Windows 95, 98, ME, NT 4.0, 2000, or XP
  • Microsoft Excel 97 or 2000
  • One serial port (COM1 through COM4)
