Conclusions With recently available portable equipment one can effect considerable improvement in detection limits for lead in painted surfaces. Our unit is admittedly less convenient and more expensive than the currently used NaI(Tl) units, but its excellent sensitivity should provide motivation for further miniaturisation. The visual display of the X-ray energy spectrum eliminates errors due to drift and to substrate variations since the operator can make his own decisions as to definition of background. The most important point is that the device operates accurately and linearly well below the 1 mg/cm2 level which appears to be the practical lower limit of present devices. Comparison of lead levels with legally set limits as low as 0.03 mg/cm2 is feasible.
