Thus, iodine-131 is increasingly less employed in small doses in medical use (especially in children), but increasingly is used only in large and maximal treatment doses, as a way of killing targeted tissues.
These studies suppose that cancers happen from residual tissue radiation damage caused by the I-131, and should appear mostly years after exposure, long after the I-131 has decayed.
Most I-131 production is from nuclear reactor neutron-irradiation of a natural tellurium target.
Radioactive tracer isotopes are injected with hydraulic fracturing fluid to determine the injection profile and location of fractures created by hydraulic fracturing.
Much smaller incidental doses of iodine-131 than those used in medical therapeutic procedures, are supposed by some studies to be the major cause of increased thyroid cancers after accidental nuclear contamination.
Here’s the exact template I use – complete with budget built in and all: J’s Financial Snapshot.
If you’re not a spreadsheet guy and prefer something more automated (which is fine, whatever gets you to ), you might wanna grab yourself a free Personal Capital account.;)) There are a billion ways to track it, but I prefer using a plain ol’ Excel spreadsheet that I manually update at the end of every month.This forces me to stop and soak things in before moving on to the next shiny thing.The element is then dissolved in a mildly alkaline solution in the standard manner, to produce I-131 as iodide and hypoiodate (which is soon reduced to iodide).and can be released in nuclear weapons tests and nuclear accidents.It also plays a major role as a radioactive isotope present in nuclear fission products, and was a significant contributor to the health hazards from open-air atomic bomb testing in the 1950s, and from the Chernobyl disaster, as well as being a large fraction of the contamination hazard in the first weeks in the Fukushima nuclear crisis.
