Hmmmmmmm,

    Hello Radsafers, 



         Dear Niagara Falls dude.  WOW, take it slow, buddy. 

    You need to do some background research before you get all excited 

    about Niagara Falls fission products. 



          <snip>        

 

           Radioisotopes that I know travel well with groundwater are: 

     Tritium,  C-14, Tc-99, I-129 and NP-237.  There may be others.  I

think I 

     remember getting some Kd-value information from the Presto 

     groundwater computer code and its user manuals.

==============

 

Since I-129 has a 17 million year half-life and decays with a relatively

low energy beta, the folklore/joke around here is that the carcinogenic

dose of I-129 is 28 lbs in the thyroid.  In fact, because of the low

activity, it is usually measured using neutron activation, rather than

simply sitting around for weeks taking a count.   It does move right

along with the groundwater though.

 

Best regards.
