Ok, in response to the influx of comments let me first say; there is a great deal of misconception/misinformation floating around. While I do mean to try my best to correct this, I mean absolutely no offense to you in my comments below.
It’s important to understand that a banana equivalent dose (BED) of radiation is absolutely tiny. ( 0.1 micro Sv to be precise) Every day you are exposed to more than 100x this amount, simply by existing on earth’s surface. It would take MILLIONS of BED in a single day, to cause any radiation related symptoms. You *will not* get radiation sickness from rubidium unless you start eating large ampoules of the stuff (really, a quantity which likely wouldn’t even be legal to possess). A standard dose of rubidium should have a negligible to non-existent effect on your cancer risk. If it really worries you that much (which IMHO, it really shouldn’t), try stacking with decitabine or SAHA, or another anti-cancer drug that could protect against oncogene activation and mitosis checkpoint inactivation (which seems to be the mechanism by which radiation causes cancer).
Your body does not need to “cleave” or remove the chloride ion. This is an ionic compound. There are no covalent or peptide bonds in rubidium chloride. The chloride (1-) ion disassociates from the rubidium (1+) ion readily in aqueous solution. The hydrogen bonding capacity of water is adequate to separate the two ions, as is the case with all soluble ionic compounds. The MOA of rubidium is believed to be its displacement of potassium ions. None of the alkali metals build up in the body. They are all removed by the kidneys (in the loop of Henley) and you should not see toxicity from that displacement behavior unless you displace more than 30% of your entire body’s potassium. Heavy metal accumulation is really something that only occurs with the polyvalent metals of the d-block of the periodic table. I’d be far more uneasy about lithium as it really seems to break everything. Rubidium seems to have opposite effects.
Rubidium does not significantly interact with sodium or displace it from ion channels on account of the large difference in atomic radius. It does however displace potassium, with toxicity becoming apparent at 30% displacement. Lithium is to sodium what magnesium is to calcium, except much more powerful and with extrapyramidal effects. Strontium’s benefit is highly contested and its effect on calcium may not be as you believe. I do not believe that strontium has any nootropic utility (but I might be wrong on this). The only displacement of calcium I see is in bones, where it makes them stronger yet somewhat brittle. There is also strontium ranelate which is linked to similar strontium related complications. Magnesium though, does seem to displace calcium from its ion channels and in some ways for some people may have nootropic potential. If you have any further information on strontium, namely why I might be wrong, please enlighten me?
Lastly I’m sure this has utility in narcolepsy, in some manner. It would be very different than amphetamine, and possibly synergistic. It would be neither better nor worse, merely a new therapeutic mechanism. However I’m far more interested in the ability to trigger and channel pseudo-mania in healthy people. I don’t see responsible use leading to taking a dose so high, so quickly, that the person is totally unprepared for it and loses all control. As long as you titrate up, you’ll acclimate to whatever changes occur and you (as well as your body) won’t be shocked into losing control. Thus even though it may be possible, most people won’t have issues. I sincerely hope that anyone reading this is responsible and aware enough to know to take it slow and proceed delicately. Common sense should be adequate protection to this.
Cesium is pretty cool and may be more potent than rubidium however there is even less data/research on it. I wouldn't feel comfortable proposing it as the successor to rubidium (which It may very well become) until we first get some reports and trials on rubidium in the nootropic community.
I think that rubidium will almost always form an ionic bond (and really stay ionized 90% of the time since it has a very weak hold on its outermost electron). Unless you ionize the gas, rubidium will not bond to it. the connection you seem to be implicating in your idea is a covalent bond which Unfortunatley I doubt will happen. that being said, I think anything that can supply rubidium would be nootropic (with the exception of things like anesthetics which are notorious for impairing memory etc). Something I'd personally like to see done, technology-wise with rubidium, is to make a brain-selective salt such as one with orotic acid. Lithium orotate, for instance largely does not dissociate until crossing the Blood-brain barrier. However orotic acid is not a viable candidate as it is likely mutagenic.
