How long does it take for a cat to recover from radiation?
After radio-iodine treatment all cats will return to normal (“background radiation”) by 28 days. Cats can be discharged from the Centre from 4 days after treatment, although this depends on exactly how much radio-iodine is given and on how quickly the radiation levels fall.

Can I touch my cat after radioactive iodine treatment?
After radio-iodine treatment, your cat should be cured of hyperthyroidism. But they'll need careful handling for a while, to keep everyone safe. Cats who have been treated with radio-iodine therapy will remain radioactive for a period of time, and that's why great care needs to be taken.
Can I be around my pets after radioactive iodine treatment?
It is safe to be around your cats after you are treated with radioiodine therapy because even if they are in your lap, the exposure is low.

Treatment of cats for feline hyperthyroidism with Radioactive Iodine (I-131) is the preferred method of therapy (and well as in humans). It is as easy as one injection just under the skin, much like a routine feline vaccine. I-131 is safe and effective.
What are the long term side effects of radioactive iodine for cats?
Cats may also continue to show signs of hyperthyroidism, including vomiting and diarrhea, for 3-4 weeks after the radioiodine therapy as the disease continues to resolve. The risk to these cats is the simple fact that many cats in the age range when cats develop hyperthyroidism (8+ years) also develop other diseases.
Can feline hyperthyroidism return after radioactive iodine?
It is expected that your cat will return to a euthryoid state (normal) between 2 and 4 months after being treated with 131 Iodine. Hyperthyroidism is caused by hyperactive thyroid glands typically caused by a benign change to one or both thyroid glands where they stop responding to normal feedback mechanisms.

Where does radioiodine accumulate?
When taken into the body, a large percentage of radioiodine accumulates in the thyroid gland . The remainder of the I-131 is excreted in the urine and feces. Once the radioiodine is taken up by the thyroid gland (or thyroid tumor in a hyperthyroid cat), the gamma rays and beta particles are released.

Why is my cat being separated for 4 days?
One of the reasons the cat was held for four days was to allow for much of the radioactive 131 I to be excreted in urine so that the amount of external radiation exposure is significantly reduced.
How to control radiation exposure?
The three ways that we control exposures to external sources of radiation are time, distance, and shielding. Reduce the time near a source, increase the distance from the source, or use some sort of radiation absorbing shielding between you and the source of radiation and you will reduce your radiation dose .
Is cat litter radioactive?

How long does it take for a cat to show signs of hyperthyroidism?
Cats may also continue to show signs of hyperthyroidism, including vomiting and diarrhea, for 3-4 weeks after the radioiodine therapy as the disease continues to resolve.

These complications include cerebrovascular events (i.e., strokes) and the premature exacerbation of pre-existing kidney disease. Luckily these risks will diminish in time following successful radioiodine therapy and a return to a persistently normal thyroid level.
What is the risk of radioiodine?
1.) Risk to the patient: The radioiodine (I -131) used to treat thyroid disease in people and animals emits both gamma rays and beta particles. The beta particles, which are much more potent forms of radiation, travel an average distance of less than 1 mm. Because of the short distances they travel they never exit the patient ...
Why do cats never exit the patient?
Because of the short distances they travel they never exit the patient and as a result no one other than the patient is at risk from exposure to the beta particles unless they internalized the radioiodine excreted by the patient. In cats > 95% of the radioiodine is excreted in the urine.
Can you put radioactive iodine in your cat's urine?
The good news is that virtually every client will already take steps to avoid this, even when radioactive iodine in their cat's urine is not the motivation.
What happens when X-rays pass through the body?
When x-rays, or any ionizing radiation, pass through the body they cause electrons to be ejected from atoms, leaving behind positive ions. These positive ions, or free radicals, can cause damage to DNA. DNA can also be damaged directly by radiation. If DNA is damaged, there are three possible outcomes:
Does iodine help cats with thyroid disease?
When it comes to survival, the studies that have been done show that cats cured of their thyroid disease by radioactive iodine live much longer (up to twice as long) when compared to hyperthy roid cats treated by methimazole. So in this case the targeted radiation exposure is actually increasing survival for these patients.
How to avoid radiation?
Here are some ways to minimize radiation risks to other people (and pets) after you have had RAI treatment: 1 Stay at least six feet away from other people, including members of the public, family members, and co-workers, for three to 11 days.

How to treat hyperthyroid cats?
Hyperthyroid cats suffer overactive thyroid glands, circulating too much thyroid hormone through their system and affecting nearly every organ. Radioactive iodine therapy offers a cure through a simple injection that returns thyroid function to normal levels. However, because your cat will be radioactive for several days after receiving the shot, precautions must be taken during and after the treatment.
