strontium 90

I placed the steel tank near the cage, uncoiled the hose attachment, unscrewed the top, and dumped in the salts of strontium.

In the absence of baryta or lime it is filtered off, and weighed as strontium carbonate, which contains 70.17 per cent.

The solution contains the barium as baric chloride mixed, perhaps, with salts of strontium or lime.

In this last case it may be examined for barium and strontium, the former of which will rarely be present.
