Summarize this article in one sentence.
When you use a tissue, put it in the toilet to flush. Similarly, when you brush your teeth, spit into the toilet bowl. On both occasions, flush the toilet twice after use. Your bodily fluids will shed radioactive material. Disposing of them this way helps keep others safe. Put the lid down to flush. Flushing the toilet twice helps ensure the radioiodine goes down the drain instead of staying in the bowl. If you're a man, sit down to urinate so you don't splash. Wipe any urine off the toilet seat after you go to the bathroom, particularly if you splash. If you spill urine or vomit, clean up the area with toilet paper and a household cleaner. With spills, always contact the radiation clinic to find out if you need to do more to clean them. After you go to the bathroom, soap up and scrub your hands thoroughly, as you'll be passing the most radioiodine in your urine. Scrub for at least 20 seconds before rinsing. If you want to be sure you're washing long enough, try humming the "Happy Birthday" song while you scrub. Showering helps wash away what your body's shedding each day in radioiodine. However, skip baths, as you'd just be soaking in radioiodine. Plus, you're more likely to leave radioiodine behind in the bathtub. You will be sweating out radioiodine, as well as passing it in other bodily fluids. Use water to clean out the sink and tub after you use them to cut down on what you leave behind. A removable shower head works well for this purpose in the bathtub.

Summary:
Spit and dispose of used tissues in the toilet. Flush the toilet twice when you use the bathroom. Wipe down the toilet after using it. Clean your hands thoroughly every time you use the bathroom. Shower once a day. Rinse the bathtub and sink after using them.
