Just so you know, @aek.field, the Himalayas are in Pakistan.
The website you referenced seems to have mis-interpreted the data. The original data (which has no author or description of how it was collected, so shouldn't be trusted wholeheartedly) can be found here: http://themeadow.com/pages/minerals-in-himalayan-pink-salt-spectral-analysis and shows that no radium, uranium, or polonium was detected.
Thallium, a suspected human carcinogen, is only present in the salt at concentrations of 0.06ppm. You consume 2ppb of thalium from your daily food intake. To put this in perspective, total thallium from a days worth of food is roughly 0.01mg; where as, in a pinch of Himalayan salt, there is roughly 0.000000018mg. This means you would need to consume 555,556 pinches (167kg) of Himalayan salt every day to match the amount you naturally consume. You will die from hypernatremia before you receive a toxic dose of thallium. Also, thallium is naturally found in soil at concentrations of 0.3-0.7ppm, eleven times more abundant than in Himalayan salt.
Lastly, you mention concerns for fluoride, which I shall not comment on for the sake of the original discussion: trace minerals in salt. Well, the data reveals that no fluoride was detected, so there are no concerns for those who choose to avoid fluoride.
In summary, of all the radioactive and poisonous elements you thought to be within Himalayan salt, none were detected (besides an incredibly tiny amount of thalium that will kill you from a salt overdose before thallium poisoning).
