Excerpt: 

Radioiodine therapy has been used successfully for more than 60 years. The treatment of thyroid diseases is one of the most frequent medical uses of radioactivity that results in radiation exposure to family and others. Protocols for treatment with I-131 differ slightly from country to country and from hospital to hospital, with varied radioactivities being administered and instructions given on how to protect others from radiation exposure for differing lengths of time. There are significant differences in these restrictions to normal behaviours between I-131 thyroid treatment for cancer and treatment for other diseases, such as hyperthyroidism.
