Radioiodine isolation

[johann]

Hello everyone!,

I was diagnosed with papillary thyroid carcinoma and I had a thyroidectomy last February and last week I had Radioiodine Therapy (30mCi), stayed one day at the hospital and then I went to an an isolated cabin for a couple weeks (Still here). My wife is 20 weeks pregnant so I want to be extra careful so I bought a device to measure radiation level (quartarad.com/product/radex... and according to the included guide my radiation levels after 7 days are still dangerous and my isolation is supposed to end next Friday so I was wondering how long should I expect to continue to produce that sort of radiation? Anyone has also measure this?

Thanks a lot!

Johann

There is a initial suggested timeline in this reference, not exactly what I was lookign for but it's a start: thyroid.org/wp-content/uplo...

Day 10 and my radiation level at 46cm (18 inches) from my neck is 1,30 µSv/h, according to the manual:

- 1.25 Real risk of cancer if exposed for a year

- 4.17 Real risk of cancer if exposed for 90 days

So with this value I guess I am something in between, still wondering when would it be safe to go home...

I was under the impression that, whilst body emissions are important, the more dangerous issue is in waste - hence things like double-flush of toilets, and washing clothes, bathing facilities, etc.

Mind, that is only from memory!

Thank you, I just wonder apart from the waste, after that first phase, if still being a moving radiation emitter could be harmful for anybody else and in what circumstances and levels.

I'd really like to help but have absolutely no knowledge beyond what is readily available online.

You just might find something relevant here:

You deserve commendation for your consideration towards those around you.

I suggest you contact the radiation dept. at the hospital you were at and ask the radiologist exactly when you should be safe.
