The determination of lead in environmental air using a radioisotope X-ray-fluorescence unit
The International Journal of Applied Radiation and Isotopes, 1982The feasibility for the development of a portable radioisotope excited X-ray fluorescence unit, able to detect Pb in air samples, was studied. The unit employs a 0.6-mCi 109Cd source and a Xe-filled proportional detector. The sensitivity of the method was found to be 15 micrograms of lead per cubic metre of air.

In this paper, we demonstrate remarkably improved efficiency over various conventional betavoltaics with critical energy loss problems. Radioactive sulfur (35S) was uniformly infused within a semiconductor material (selenium) and volumetrically encapsulated in the harvesting betavoltaic cells.

Abstract Proton beam of energy 14.7 MeV have been used to study the reaction cross sections and the excitation functions of the possibly produced gold radioisotopes using stacked foil technique. Five Au radioisotopes namely, 193Au, 194Au, 195Au, 196Au and 198Au have been measured and discussed in the energy range from the proton reactions threshold ...

Abstract The sulphur content of fuel oils and the lead content of gasolines can be determined in a single measurement by a simultaneous detection of scattered and transmitted low-energy X-rays. A prototype immersion probe has been developed and a precision of 0.02% sulphur and 20 ppm lead obtained for a counting period of 1 min.
