    4. Radiation Safety

    5. Radiation Safety The XRF analyzer produces radiation when energized; users must understand & follow safe work practices Radiation exposure is negligible with proper use

    6. XRF Safe Work Practices Never point the instrument at anyone, whether energized or de-energized When performing an analysis, the analyzer should always be in contact with the surface of the material being analyzed and the material should completely cover the aperture Make sure that co-workers are at least 3 paces away during an analysis 1. Under no circumstances should the X-ray tube be on and emitting X-rays when the instrument is not in use. Note: The warning lights on the instrument will blink on and off whenever the X-ray tube is on and emitting x-rays. A continuous light indicates minimal power to the X-ray tube. The instrument may be safely transported while in this mode. In the unlikely event that the X-ray tube continues to emit X-rays when a sample is not being measured, disconnect the battery pack and immediately notify the manufacturer 2. When performing an analysis, the analyzer should always be in contact with the surface of the material being analyzed and the material should completely cover the aperture. 3. In the event of an emergency where it is believed someone may have received x-ray exposure (e.g., reddening of skin), or if there is an apparent malfunction of a safety interlock, the FDPMU Radiation Safety Officer shall prepare an incident report and forward it to the cognizant Radiation Health Officer at Navy Environmental & Preventive Medicine Unit No. 2 (FDPMUs 1, 2, 3 and 7) or Navy Environmental & Preventive Medicine Unit No. 5 (FDPMUs 4, 5, 6 and 8) with a copy to Expeditionary Preventive Medicine at Navy & Marine Corps Public Health Center.

    7. Forbidden Testing Configurations Never test samples as shown in the photos below: Dose to fingers and/or hand if misused as pictured could be as high as 28,000 mrem/hour Over-exposure could occur within 2 hours ..

    9. Trigger Lock User must release software trigger lock before testing Once released, trigger lock remains disabled for 5 minutes If a test is not conducted within 5 minutes, the trigger lock will re-engage

    10. Deadman Trigger Trigger must be held for duration of test Releasing the trigger ends test This ensures that users intentionally start each test Prevents user from walking away and leaving instrument on If user picks up analyzer and inadvertently pulls trigger, test will end as soon as trigger is released

    11. Software Proximity Sensor Instrument will shut off after 1-2 seconds if sample is not present Analyzer checks count rate, if count rate is not significantly above air rate, x-rays shut off

    12. Radiation Warning Lights Light on continuously indicates that there is power to the X-ray tube A Flashing light indicates that a test is in progress and X-rays are being emitted The display on the back of the instrument provides a testing message to indicate that the X-ray tube is energized, the analysis window is open and X-rays are being emitted Continuous light indicates there is minimal power to the x-ray tube. It is producing low level x-rays internally but the shutter provides adequate shielding to keep x-rays levels below detection. The instrument may be carried around in this configuration. Light flashing – tube is at full power, shutter is open and x-rays are being emitted from the analysis window. The analyzer should only be pointed at a sample (the surface of the ground) or be in the test stand with a sample resting on the analysis window.

    13. Radiation Exposure Standards 5 rem per year (whole body) 50 rem (extremity or individual organ) 0.5 rem during pregnancy 0.05 Sv, .5 Sv and 0.005 Sv respectively. Exposure standards are based on the conservative assumption that there is no safe level of exposure. In other words, even the smallest exposure has some probability of causing an effect, such as cancer. This assumption has led to the general philosophy of not only keeping exposures below recommended levels or regulation limits but also maintaining all exposure "as low as reasonable achievable" (ALARA). ALARA is a basic requirement of current radiation safety practices. It means that every reasonable effort must be made to keep the dose to workers and the public as far below regulatory limits as possible The dose limit to non-radiation workers and members of the public is two percent of the annual occupational dose limit. Therefore, a non-radiation worker can receive a whole body dose of no more that 0.1 rem/year from industrial ionizing radiation. This exposure would be in addition to the 0.3 rem/year from natural background radiation and the 0.05 rem/year from man-made sources such as medical x-rays. 0.05 Sv, .5 Sv and 0.005 Sv respectively.

    14. Dose Rate at the Window Dose at the exit of sampling window is approximately 28,000 mrem/hr

    15. Maximum Potential Dose for Operators* <0.1 mrem/hr X 12 hr/day = 1.2 mrem/day X 80 days/year = 96 mrem/year .096 rem/year, or < 0.2% of allowable exposure/year although the exposure rate directly in front of the detector window can be as high as 28 R/hr, no measurable dose to an operator is expected if the manufacturer’s instructions are followed, and no interlocks are bypassed. although the exposure rate directly in front of the detector window can be as high as 28 R/hr, no measurable dose to an operator is expected if the manufacturer’s instructions are followed, and no interlocks are bypassed.

    20. XRF OPERATION Standardization is required: each time the analyzer is initiated/restarted every 4 hours of continuous operation Any time there is a sudden, large change in ambient temperature The procedure is automated and must be competed before analyses can be performed Results of Standardization must be recorded in the Utilization Log Before performing tests, it is necessary to standardize the instrument. This automated procedure involves collecting a spectrum on a known standard (Alloy 316) and comparing a variety of parameters to values stored when the instrument was calibrated at the factory. If there are any problems with the instrument, they will be indicated by an error message. The standardization procedure takes about 1 minute. Standardization must be done any time the analyzer hardware is initiated or restarted and must be repeated if the instrument is operating for more than 4 hours. Each time the analyzer is restarted, the operator will be prompted to standardize the instrument before performing any measurements. This is indicated by the message “Standardization Required. Please place a standardization clip over the analyzer window. Then tap here to standardize.” on the analysis screen. It is not possible to start a test before standardization.

It is strongly recommended that you use this option and export data on a daily basis. 3. After choosing which readings to export, you may choose to export all data, or just data from a specific mode. Selecting the arrow to the right of the mode to export will open a drop-down menu. Select the mode for which you want to export data.

    33. XRF OPERATION 1. All standardization data are stored as results files. These data are automatically included in exported results files when the selected “Mode to export” is All. Additionally, it is possible to export only the standardization data by selecting Standardization as the “Mode to export.” 2. When the proper selections have been made, select OK. A Save As box will appear. Select the folder in which you want to save the data, and name the file. The file Type will always be Comma Separated Values. The recommended Location is Main memory and Folder is None. This will export files into the “My Documents” folder in the main Memory of the PC. If you select a File Name which already exists, you will be asked if you want to replace the existing file. If you do, select Yes. Otherwise select No and choose another file name. 3. A status bar will indicate the progress of the export. It may take several minutes to export readings. Daily downloading and weekly erasing of data simplifies and shortens this procedure. 4. When all readings are exported, a message will appear confirming the export. Tap ok to acknowledge and clear the reading. 1. All standardization data are stored as results files.

    37. In situ testing: In situ testing is performed by pointing the analyzer at the ground. An area for in-situ analysis should be prepared by removing large rocks, vegetation, and debris. The soil surface should be flat and compact prior to analysis. The XFR analyzer should be placed in the in-situ adaptor and held firmly on the ground to maximize contact with the ground. The unit should not be moved during analysis. Analysis of water-saturated soils should be avoided. Since dirt can accumulate on the analyzer window, the window should be wiped clean after each analysis. The window should also be checked to ensure it is not ripped or punctured.

    38. Bagged or prepared sample testing: The Standard Soil Mode application assumes the sample to be infinitely thick. For in-situ measurements this is the case; however, for sample cup and/or bagged sample measurements, it is advisable to fill the sample container nearly full. Fill sample cups to a depth of at least ½ inch of packed soil. When analyzing bagged samples, make sure that sufficient sample exists in the bag to completely cover the window with a sample thickness of a minimum of ½ inch. This ensures that the sample is as uniformly thick as possible from analysis to analysis. The Innov-X System bulk sample test platform must be used when analyzing sample cups or bagged sample. Never hold prepared or bagged samples while testing!Bagged or prepared sample testing: The Standard Soil Mode application assumes the sample to be infinitely thick.
