The Soviet secret police have managed to have an former Sovet agent poisoned with Thallium which was subjected to intense bombardment with radiation. When absorbed into a human host, this Thallium would break down and disperse throught the organism. The agent in quesion was sent to kill an important anti communist, and NTS president. This agent's name was Khohlov and it happened in the 1950's. This element is also known to make one's hair fall out without it being radioactive.

Then you are missing out

Thallium is EXTREMELY poisonous it was used as Rat Poison in the 19th century banned in 1975

@kamspioneerclass Ah, ok then.

[kamspioneerclass]

@WeaselWJ Well yes, I didn't mean to imply that all Thallium was radioactive; I thought Mr. Nikolai was talking about a case I'd heard of, and I remembered it as involving a common radioisotope of Thallium (although I heard about it a long time ago).Thanks for the correction on the Geiger counter, though, I didn't know that (clearly).

[WeaselWJ]

@kamspioneerclass Nope, the most common isotope of Thallium is perfectly stable. Also, a Geiger counter can detect both Alpha and Gamma radiation and also Beta radiation. So you're wrong on both points.

Love the vids...thx professor!

@Nikolaii257 It is radioactive, actually. You simply can't detect it using a Geiger counter or anything of the sort because it emits alpha radiation (as opposed to gamma radiation). I did read an article (I believe in Popular Science) about this, though.

haha i like the crazy proffesor look...

Once inside the body Thallium causes nerves and muscles to atrophy and die. Victims typically experience burning sensations in their limbs, upset stomachs and hair loss. In severe cases the symptoms progress to tremors, delerium, paralysis, coma, and death.  GO Thallium GO.

Just reading a true story about Thallium poisoning. The ex-head chemist of a crank lab in the 70's, which have been known to use Thallium III Nitrate. Let it oxidise and Ti(NO3)3 decomposes to Thallium I Nitrate, wich is the only form that will disolve in Coca-Cola without changing the color or making it foam and lose more carbonation then normal tampering would allow.
