Abstract

A process for testing for lead-210 comprises precipitating the lead as sulphate, dissolving the lead as chloride, separating the lead by an ion exchange process, and, after a known delay counting the beta particles from the daughter bismuth-210 through a shield stopping beta particles from lead-210 and alpha particles from polonium-210. To test an effluent from radio-chemical laboratories or processing plants, a sample of the effluent is treated with sodium sulphate in the presence of lead and strontium carriers; the sulphate precipitate is treated with sodium carbonate, dissolved in hydrochloric acid, and the solution passed through an ion exchange column; lead is eluted from the column with water and precipitated as chromate. After five days the bismuth-210 formed is counted through an aluminium absorber. In order to purify the bismuth-210 further, the precipitate is disolved in hydrochloric acid with a bismuth carrier, the solution passed through another ion exchange column, and the lead is removed by washing with water. Bismuth is eluted with sulphuric acid, precipitated as phosphate, and counted.
