Dear SR / SRA:

For the treatment of your illness, we have given you a radioactive substance called 131-Iodine. This substance will remain in your body for several days until it disappears completely through the urine, because it eliminates itself. While this is beneficial for you, certain precautions must be taken in order to protect the people with whom you live. Therefore, we recommend that you follow these instructions for the next 7–10 days (from xx-xx-xxxx to xx-xx-xxxx):


• When using the toilet, you must pull the cistern several times (approximately 4 times).
