In-vivo K-X-ray fluorescence (KXRF) was applied to the noninvasive measurement of the lead levels in the midtibial diaphysis. Blood and soil lead concentrations were also determined. The mean bone and blood lead levels were +/ parts per million and +/ micromoles per liter, respectively. X-ray Fluorescence (XRF) Description. Subsurface contaminant plumes are usually characterized using a drilling rig to install monitoring and groundwater samples are collected and sent to a laboratory for analysis. This traditional approach is slow and costly. In its most common use, an X-ray Fluorescence (XRF) sensor is employed with a cone penetrometer for real-time, in-situ field.

OSHA does not consider X-ray fluorescence (XRF) to be an acceptable method of analysis. As stated in your letter, XRF analyzers are generally considered accurate when concentrations of lead Colorado book paint exceed 1 mg/cm 2.
For the purposes of occupational health, these levels are considered substantial and may easily present an exposure hazard. X-Ray Fluorescence Lead Survey The report, “An X-ray Fluorescence Sur-vey of Lead Contaminated Residential Soils in Leadville, Colorado: A Case Study,” presents information on the use of field-portable X-ray fluorescence (FPXRF) to determine the spatial distri-bution of lead concentrations in residen-tial soils contaminated from theFile Size: KB.

Soil, water and air can all be polluted by harmful substances, and this contamination can be directly toxic or can pass into food or other products for human consumption.
The performance of the Spectrace TN portable X-ray fluorescence (P-XRF) instrument for in situ sampling and analysis of contaminated soil was evaluated. The method was compared with laboratory analysis of the samples using ICP-AES and XRF as established methods for the assessment of contaminated land.
