Thanks a lot Sir. Sir, 1 last query- In our home the toilet waters and wastes are stored in a closed tank(the tank is exposed to soil at it's buttom at about 5 feet depth) and her bathing water and tooth brushing water are flushed to an open small unused pond. Both tank and pond are backside of my house. Can the I-131 be exposed via soil ???? Because since immediately after the treatment she is isolated in home

Brief Answer:
The water and soil contamination is not a serous concern

Detailed Answer:
Hi,
Thanks for writing in to us.

Soil contamination due to treatment with 100 mCi I131 as mentioned in your query is not a serious concern. The water in the tank will get diluted and disintegrated in sometime and will not enter the soil in harmful quantity.

You are safe from contamination if she is isolated in home.
