Abstract

A detector of lead in air will be described. It utilizes a spark source for the excitation of the lead spectrum, a small quartz spectrometer for the dispersion, and a quartz Geiger-Müller counter for the detector of the radiation. The lower limit of detection is of the order of 20 micrograms of lead per cubic foot of air. The instrument is mobile and ideally suited to locate areas of high lead concentration in air.
