... Your point about having to ingest the radiation is one I was really toiling with myself it just doesn't make sense... Russia is going to poison all of us? What is their target patient population? Three?
I don't know HEPH but I'll take a peek. That one as I remember you picked up off the biggest losers list but not CBLI? So perhaps you can merge your filtering system to include other variables besides the overreaction big swoon-- which I agree is a constant scalping money maker but maybe not the best way to stay leader of the pack-- which is important in biotech.

Well, to address your first question. There are three conventionally recognized mechanisms of "early fatality" for ARS, which i'll refer to by target organ and respective approximate LD50 (in Gy) in their usual order of importance (assuming no treatment) for "PROMPT" internal and external radiation doses (more on that later): 1) bone marrow @ ~4 G, 2) GI @ ~8 Gy, and 3) lung @ ~12 Gy.
For any conceivable exposure to the usual mix of fission products created by the literal "splitting" of uranium and plutonium atoms in what would be released from a reactor accident or a nuclear yield from a criticality or a nuclear weapon detonation (and this includes both internal and external radiation), the almost TOTALLY dominant mode of death is due to bone marrow damage. That is what HEPH's Neumune drug is used to treat. It's a non-androgenic steroid which raises the LD50 to marrow by roughly 50%.
Now, if it's external penetrating gamma and neutron radiation, all organs (except ... ahem ... testes?) get around the same dose, so it's obvious that the deaths you'd see would be due to bone marrow dose with an LD50 of ~4 Gy. Sr-90 is an important fission product (go back to atmospheric weapons testing and all the talk about Sr-90 in milk) and take account of the fact that Sr is in the same column of the Periodic Table as calcium, and the body will metabolize Sr the same as Ca and it will go to the bones, but actually it's going mostly to BONE SURFACE, not the marrow, and Sr-90 is a beta emitter so even inhaled (or ingested) Sr-90 may not be that important for its internal dose to the bone marrow.
Well, maybe i should cut to the chase. Go up above to the 1-2-3. the bone marrow LD50 is the lowest so unless there is something that "seeks out" another organ (such as radioiodine to thyroid), "bone marrow death" will be clearly dominant over GI and lung.
For GI death to occur (and it takes longer than bone marrow death) so if someone gets the respective LD50s to both organs (marrow and GI) you would need to have something either inhaled or ingested that is an alpha or beta emitter. Both have short range of travel and are shielded by a thin layer of tissue.
So for ARS to kill someone by GI syndrome, they would have to ingest something like the Po-210 of the unfortunate Mr. Litvivenko. Mr. L. is dying (apparently) of GI or lung syndrome and not marrow (hematopeoesis) because he ingested an alpha-emitter:
http://en.wikipedia.org/wiki/Polonium . So his bone marrow was a smaller fraction of its LD50 than for the other two modes of death.
But ingestion is not the ONLY way to get a GI dose from an alpha or beta emitter. Dependiong on particle size, the mucosal layer of the breathing tract will trap some particles and they're "cleared" to the stomach and then pass through like other things ingested. Basically, we swallow mucus and it goes into the GI. So you can die from inhaled material via GI syndrome but it would have to be an alpha or beta emitter (and also be an element that is not a "bone seeker").
So that concludes today's lesson in health physics as it applies to ARS, and how that affects CBLI versus HEPH and Neumune versus Protectan. I don't understand why DoD is as interested as Fonstein is claiming for a protection against GI syndrome unless, as you say, they expect the military's food to be radio-contaminated (at levels so high the food truck would never make in onto a military base!).
Fonstein yesterday didn't seem to actually understand all of that, which was frightening to me.
And as far as my finding HEPH, i became aware if its news releases pertaining to RDDs, which i was working on professionally at the time. I became interested in it as it pertains to public safety from radiological terrorism. So i added the stock to my watchlist. Then, i'm certain, one day some news came out and it hit the Biggest Loser list and i read the story and of course it was already on my watchlist, so it didn't take me much time to figure out that it was a good time to buy, which it was. And then news came out which made it go up, which as usual was an overreaction, so i sold. And then it fell again and was consolidating so i accumulated. And then some news came out that made it goi up so i sold. And now i have a relatively small position but would add to it if any bad news comes out that makes it tank unduly. Get the picture?
Anyway, i'm STILL BEATING MYSELF UP over not selling my CBLI when it was over $13.
Is there ANYTHING that could be seen with a technical indicator of the attached 4-day minute-by-minute chart of CBLI that SHOULD have told me to sell when it reached $13 and kept going or when it hit $13.99 and started falling????
Any technical analyst chart readers???????
Gee whiz. I made a JPG but how do i attach it to a post here?
And, finally, as far as staying "at the top of the pack" per what SI said in the quote above .... that may be your style, but it's not mine. Remember what my handle here is? it has "BOTTOM FEEDER" in it. i'm interested in buying low and selling high.
if a stock is up already, i'm simply not interested in it. period. if i buy a stock cheap and then it keeps on going .... hey ... like CBLI did ... i held on to it. but i guarantee you that if i looked up my original trading, i was buying it on DIPS, not rallies.
I forget how long i watched it before buying. It doesn't matter. I don't buy stocks that are flat-lining.
