N2 - We have constructed an external beam PIXE system for trace element analysis of biological and environmental samples. Analytical procedures that include sample preparation and PIXE setup are described for analysis of maternal scalp hair, amniotic fluid, human placenta, and colostrum samples. The study was conducted to obtain trace element data on important biological tissues for incorporation into a large data base that will be used to assess fetal and infant well-being. A 3.5 MeV external proton beam was used to produce X rays in the samples after they were low-temperature ashed. Detection limits for essential and toxic elements are less than 0.4 μg/g for a 6 min irradiation time.
