One miligram emits the same amoung of radioactivity than 5 gram of Radium. The radioactivity of 1 gram of Ra.. which is basically 1 Curie
So we are dealing with 150 GBq.. roughly
But the realtion between the decay and the energy is not straigthforward. I do nto know how many Bq produce 1 Sievert. It actually depends onthe enrgy carrier. Int his case alpha particles. Bq is just the time per second that an alpha particle hits ana rea..how many energy carries 150G alpha particles?
From this you get the enrgy accumulated.. this msut be divided by one or two other of magnitudes depending onthe tissue, the distance and all that stuff.
A pleasure I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
At a committed effective dose equivalent (CEDE) of 5.14×10^−7 Sieverts per Becquerel (1.9×103 mrem/microcurie) for ingested 210Po and a specific activity of 1.66×10^14 Bq/gram (4.49×103 Curies/gram)[4] the amount of material required to produce a lethal dose of 10 Sieverts would be only 0.12 micrograms (1.17×10−7g). The biological halflife is 50 to 30 days in humans.
One order could be explained by effective dose and another rounding problem, tissue staff, effective values and so on. But three orders of magnitude is too much.
Problem is micrograms are very difficult to transport..
I quite do not believe I can be so off the park. and that micrograms and not miligrams is the appropriate order of magnitude.
I will check it again.
Although miligrams would make the mixture extremelly easy...while micrograms.. well you need certain basic infraestructure.. first to trasnport the Po 210 probably mixed among other powder and then transported.. homogonize the mixture adn then mix it with the liquid.
It tkaes a ini-lab... something anybody can get ( i can do it in my house I know ehre to buy the stuff).. but it needs some tiem indeed.
It says that the specific activity is 1.66 10^14 Bq/grt when actually Po 210 is like 5 gr of Ra. 1 Ra generates just 1 Curie or 3.7*10^10
So we are talking about roughly 1.6 *10^11 and not 1.6 *10^14... Here there are three orders of magnitude.
Am I wrong?
So if this ratio is correct I guess there is some problem with the way the energy reaches to the tissue or I had a missmatch of three orders of magnitude.
I would bet that the ratio between Bq and actual energy in the tissue is not the given in the wiki article.
I will need some proof about this ratio.
Another option is to mix the amount of polonium in another substance so that alltogether is easy to handle.. but this would require some studd that you can not have at home..
