After radioactive iodine 131 treatment how long should you wait to have small children back in your care if you recover at home not hospitalized?

To treat what? If hyperthyroidism ok in one day - but not to have them in your lap. If for thyroid cancer wait a few days - the nuclear facility will want to do a post rai scan in about 3 days - so ask them based on any uptake when it would be safe.
