“…The review by Todorov and coworkers was concerned with measurement of depleted uranium, but the same methods are applicable to natural or enriched uranium. Use of ICP-MS for analysis of uranium in bioassay samples has increased considerably in recent years (Becker 2005). Advantages of this method compared with other common techniques such as alpha spectrometry include some or all of the following: high sensitivity, low cost, ease of sample preparation, and short analysis time (Karpas et al 1996;Maxell and Fauth 2002;Hang et al 2004;Bouvier-Capely et al 2004;Becker 2005).…”

This report provides methods to interpret and apply occupational uranium monitoring data. The methods are based on current international radiation protection guidance, current information on the chemical toxicity of uranium, and best available biokinetic models for uranium. Emphasis is on air monitoring data and three types of bioassay data: the concentration of uranium in urine; the concentration of uranium in feces; and the externally measured content of uranium in the chest. Primary Reference guidance levels for prevention of chemical effects and limitation of radiation effects are selected based on a review of current scientific data and regulatory principles for setting standards. Generic investigation levels and immediate action levels are then defined in terms of these primary guidance levels. The generic investigation and immediate actions levels are stated in terms of radiation dose and concentration of uranium in the kidneys. These are not directly measurable quantities, but models can be used to relate the generic levels to the concentration of uranium in air, urine, or feces, or the total uranium activity in the chest. Default investigation and immediate action levels for uranium in air, urine, feces, and chest are recommended for situations in which there is little information on the form of uranium taken into the body. Methods are prescribed also for deriving case-specific investigation and immediate action levels for uranium in air, urine, feces, and chest when there is sufficient information on the form of uranium to narrow the range of predictions of accumulation of uranium in the main target organs for uranium: kidneys for chemical effects and lungs for radiological effects. In addition, methods for using the information herein for alternative guidance levels, different from the ones selected for this report, are described. v FOREWORDThis report provides a detailed description of uranium biokinetics and bioassays applicable to evaluation of health risks from potential intakes in an occupational setting. The report addresses both the radiotoxicity and chemical (renal) toxicity of uranium. For reference occupational exposure scenarios, predictions of the time-dependent concentration of uranium in tissues and bioassay are based on biokinetic models currently recommended by the International Commission on Radiological Protection (ICRP). The ICRP's models and default assumptions for uranium were based primarily on data for human subjects exposed to uranium in controlled studies or in occupational or environmental settings. In addition, the ICRP considered an extensive database for uranium in laboratory animals. Sensitivity studies examine the robustness of these models and assumptions to ensure that radiation doses and accumulation of uranium in the kidneys are not underestimated. For example, analyses indicate that a default 5 µm activity median aerodynamic diameter particle size can lead to an underestimation of radiation dose as well as the concentration of uranium in the kidneys if inhal...

“…ICP-MS has been used to determine 129 I in contaminated environmental samples with high level 129 I content such as sediments, groundwater samples, soil and seaweed (Izmer et al, 2003;Izmer et al, 2004;Becker, 2005;Brown et al, 2007;Li et al, 2009). The lowest detection limit of the method reported as 129 I/ 127 I isotopic ratio is 10 -7 .…”

“…Inductively coupled plasma mass spectrometry (ICP/MS) has been increasingly used for precise and accurate determination of isotope ratios of long-lived radionuclides at the trace and ultratrace level due to its excellent sensitivity, good precision and accuracy [Becker, 2005]. An X series using Plasma Hot Screen (Thermo Electron Corp., USA) was used in this study for qualitative analysis of SRS DNAPL.…”
