1. Canada Maximum exposure under ICRP regulations is 500 mSv for radiation workers and 50 mSv for the general public Thus continuous operation provides a dosage 250 times lower for a radiation worker and and 25 times lower for the general public Exposure to Torso is so low it cannot be measured To be conservative we use the same figure as the trigger lt 0 1 mrem hr Annual exposure using operating conditions above is lt 40 mrem 0 4 mSv Maximum allowed is 5 000 mrem under OSHA and 20 mSv under ICRP for radiation workers 1 mSv for general public For the x ray energy emitted by portable XRF analyzers 10 60 keV region the bone in the fingers will absorb radiation about 3 5 times more than soft tissue so the bone would be at an elevated radiation risk compared to soft tissue For this reason no person shall hold a test specimen in front of the window with the fingers in the direct beam or direct the beam at any part of the human body Reference Health Physics 66 4 463 471 1994 Misuse Example 1 Operator holds samples in front of window with fingers such that fingers are directly in the primary beam Do not do this For fingers at the port in the primary beam the maximum dose to the fingers is 28 160 mrem hr Assume an operator performs a 10 sec test typical The dose to the operator s fingers or hand is 28 160 x 10 3600 78 mrem If the operator did this 641 times year they would exceed the allowable annu
2. Example of Error The operator collects a bag of sample performs XRF analysis on one part of the bag and sends the bag or part of the bag of sample to a laboratory for analysis The laboratory reports a very different value than the operator obtained with the XRF Problem Since the sample is very non homogeneous the operator did not obtain a result that was representative of the entire bag of sample The lab analyzed a different part of the sample and obtained a very different result due to the non uniformity of the sample The solution to this problem 1s at a minimum to test several locations in the bag of sample and report the average value Also note the differences between the tests as this 1s indicative of the non uniformity of the sample Operator should send entire bag of sample to the lab and instruct lab to prepare the sample before removing sub sample for lab analysis Best Practice The operator should homogenize and prepare the entire bag of sample and then collect a sub sample for XRF testing After testing the same sample should be sent to the lab Section 7 Common Interferences An interference occurs when the spectral peak from one element overlaps either partially or completely with the spectral peak of another If the XRF is calibrated for both elements CASE 1 1 e the one causing the interference and the one being interfered with it is generally capable of correctly handling the interference In this case the elem

10. Note It would be highly unusual for an operator to somehow lock up the analyzer with the x ray tube powered on This would require the operator to crash the iPAQ during an analysis If this happens the analyzer will shut off the x ray tube 10 seconds after the last communication with the iPAQ However if at any time the operator believes the x ray tube is on and no test is in progress powering off the analyzer and 3 13 Innov X User Manual Version 2 1 restarting will automatically shut down the x ray tube and close the shutter It will no longer be possible to produce x rays at this point 3 11 DOSIMETER BADGES Dosimeter badges are provided as a monthly service by several companies listed in this section see below The badges are generally provided monthly and the operator returns the previous month badges to the company for analysis The operator receives a monthly report showing any personnel with readings higher than typical background radiation Dosimeter badges are required by some states and optional by other states Innov X recommends that operators wear badges at least for the first year of operation as a general precaution to flag any misuse of the analyzer Dosimeter badges are available for the torso generally worn on the belt loop or shirt pocket and are available as ring badges The best single badge to obtain is a ring badge that is worn on a finger on the opposite hand used to hold the analyzer This will record acci

The operator should use the S10 silicon dioxide blank provided with the analyzer The purpose of this test is to verify there is no contamination on the analyzer window or other component that is seen by the x rays Method 6200 recommends an instrument blank at least once per day preferably every 20 samples For either in situ or prepared sample testing the operator should just test the SiO blank to be sure there are no reported contaminant metals Method Blank The purpose of the method blank is to verify that cross contamination is not introduced into samples during the sample preparation process Method 6200 recommends following the sample preparation procedures with clean SiO once very 20 prepared samples This QC step is not required if the operator is not preparing samples Calibration Verification Innov X provides NIST standard reference samples for calibration check by operator The operator should perform a 2 minute test on a NIST standard The difference between the XRF result for an element and the value of the standard should be 20 or less Calibration Verification should be performed upon instrument startup and periodically during testing Note Innov X recommends a calibration check every 4 hours EPA Method 6200 recommends a calibration check every 20 samples NIST reference standards are generally applicable for Pb As Cr Cu Zn Innov X provides additional reference standards for other RCRA or Priority Pollutant metals inc
