Lutetium is also used as a phosphor in some LED light bulbs, although its extremely hard to separate it from other rare earth elements.
Thallium: thallium oxide used in some high index refraction glass, thallium halogens (especially bromide and iodide) are used in infrared optical
devices. Thallium sulfide is used in photo-resistors and thallium-mercury alloy (8-9% thallium) is used in low temperature thermometers.
Thulium- Thulium-chromium-holmium alloy is used in some lasers, especially those used in surgery. Also, it is used in some portable X-ray devices.
Basically all of the above mentioned elements are hard to get, unless you stumble upon some broken parts of the above mentioned devices.

That does seem rather high. Do you live over a Uranium mine?
From Wijki:
The average concentration of radon in the atmosphere is about 6×10−20 atoms of radon for each molecule in the air, or about 150 atoms in each
ml of air.
Your concentration is 6x10-6 or about 10^14 higher than normal.
Maybe I don't understand?
What is the radiation level in Bq/m^3 (Becquerels / cubic meter) or picocuries per liter ( pC/L)

Perhaps "White Yeti" refers to his glowing in the dark?

Just a joke.
Lighten up guys. I don't know if I have radon in my basement, although I know some of my neighbours have radioactive basements.
In any case, you can't collect and store radon, it has a half life of a few days. The best you can do is find some uranium ore, or yellowcake and put
it into a vial. if you've gone through all that trouble, you might be the proud owner of a few atoms of radon. I, personally, wouldn't bother. I'd
rather take the air in my basement, put it into a glass vial, and say it contains traces of radon.

But, as you said, it wouldn't contain traces of radon for long. If you kept 1 mL of air in a vial and it contained about 7x the average amount (1000
atoms per mL...) it would be all gone in about 5 weeks. It would be better to just keep a beaker sitting there open to the air. That way it would
always contain at least one radon atom.
