[ RadSafe ] Rad Toolbox [[was Radon pCi/l to mRem/hr]]

[Jaro]

I installed Rad Toolbox software on my PC, thinking it will be a handy tool
to have.

But I was a bit disappointed, when I tested it to see how it displays data
on Sr-90 decay.
Like many other reference sources, it omits the Y-90m isomer, which is
normally the intermediate decay product, prior to Y-90.
If it wasn't important, I guess I wouldn't mind very much.
But in this case, if users are unaware of the intermediate decay product,
they are led to believe that Sr-90 is a radioisotope energy source without
any gamma emissions (thus very desirable, as bremsstrahlung X-rays are
easier to shield than gammas).

I wonder how many other such omissions are present in Rad Toolbox & similar
software ?

Is anyone aware of any software that is more accurate ? (Thnx)

There is a perfect program for this task. The software name is Rad Toolbox.
It can be downloaded from http://ordose.ornl.gov/downloads.html. Click the
"Decay Data" box from the menu when running the program. Hope this helps.

Need a little help.
I recently tested my home for radon gas using a commercially available
passive alpha-track detector. Results were reported in picocuries per
liter. I would like to convert this to millirem per year. Can some one
point me in the right direction to find the formula for this?

Thanks
Doug
