Initial study of 210Pb in indoor air.
An exploratory program was undertaken to determine the feasibility of measuring the indoor air concentration of 210Pb. Low flow rate pumps and membrane filters were used to collect samples in an office. The air filter samples were stored for 1.6 y and 210Po was chemically separated and measured by alpha spectrometry. Unsupported 210Po was also determined in air samples collected at a later time. The average air concentrations were 150 microBq 210 Pb m-3 and 12 microBq 210Po m-3. The average indoor to outdoor ratio of 210Pb in air is estimated to be 0.25.
