If you're looking for reasons to avoid RAI, you might be interested in
this file, sent to me through this group shortly after I joined (a few
years ago):

Top Reasons Not To Have RAI
1. It's permanent; once you swallow this there is no changing your mind
and starting over.
2. Since the science is inexact and dosage a guess at best, it may take
years to be fully effective, or it may have to be repeated (1)
3. Can bring on (induce or cause) thyroid storm as the dying gland
"dumps" (releases) excess thyroid hormone and thyroid antibodies into
the body; RAI also stimulates immune cells within the thyroid gland to
produce more thyroid antibodies. (2)
4. Graves disease is an auto-immune disease, not a disease of the
thyroid, so killing the thyroid doesn't stop the disease process;
without adequate thyroid tissue, the antibodies that cause
hyperthyroidism may go on to affect orbital or dermal tissue, causing
Graves' ophthalmopathy and pretibial myxedema.
5. Results in hypothyroidism.
Whoever said hypothyroidism is easy to treat, was mistaken. Because of
the effects of thyroid antibodies, radiation-induced hypothyroidism is
more difficult to treat than naturally occurring hypothyroidism.
Hypothyroidism caused by treatment for hyperthyroidism is known to cause
depression and anxiety. In one large Dutch study, "over one third of
patients with a full-time job were unable to resume the same work after
treatment. It appears that many of these patients are in need of
psychological support (3)
6. Being hypothyroid is neither less debilitating nor less dangerous
than hyperthyroid. With hypothyroidism one is at risk of myxedema coma
which can be more deadly than thyroid storm. This results from improper
monitoring and labs tests, keeping us in a hypO state. After
radiation-induced hypothyroidism develops, it takes only 6 weeks without
thyroid replacement hormone for patients to fall into myxedema coma.
7. Increased antibody titers after RAI skew lab test results, adding to
treatment difficulties. In particular, the widely-used TSH test is
influenced by TSH receptor antibodies, causing falsely decreased levels.
8. RAI, aka spent nuclear fuel ("nuclear waste", in other words) is
absorbed by other organs and can cause cell death or DNA mutations. RAI
is absorbed, in smaller amounts, by other organs besides the thyroid,
including breast tissue, the genitals, pancreas, and the gastric mucosa.
9. For up to 4-8 weeks after dosage, we're exposing those around us to
radioiodine. This is demonstrated by patients registering measurable
radioidine in airport and other screening devices.
10. Studies show an increase in cancers, especially of the thyroid gland
and small bowel, after RAI. (4)
11. Possibility of damaging the parathyroid, causing hypoparathyroidism.
(5)
12. RAI can cause difficulty with future attempts to become pregnant and
carry pregnancies to term. RAI is known to affect the ovaries, which is
why patients are recommended to avoid becoming pregnany for at least 6
months after RAI. The 6 months recommendation was increased to at least
one year in early 2002
13. Chance of thyroid eye disease developing increases dramatically, as
RAI doesn't stop antibody production (6)
14. Chance of significant, unhealthy weight gain is increased Studies
show that weight gain is inevitable after radioiodine- induced
hypothyroidism (7)
15. Replacement hormone products currently on the market, both synthetic
and glandular, are not comparable to our own hormone, and in some
people, never feel "right".
16. Ongoing problems as the gland gradually dies, necessitating close
medical surveillance and replacement hormone dosage adjustments which
usually does not happen unless a patient is educated and proactive in
their disease and treatment. Within one year after RAI, most patients
are on a dose of replacement hormone equivalent to 0.1mg levothyroxine;
5-6 years post RAI, most patients are on 0.175 mg levothyroxine because
of the progression to autoimmune thyroid failure.
17. Increased risk of developing fibromyalgia like symptoms
18. For most GD patients, medication with ATD's creates a euthyroid
state similar to "normal life", and can lead to long-term remission as
well. (8)
19. As modern science explores the human genome, a cure for GD could be
found, but after RAI kills the thyroid, it wouldn't work. Current
research is directed at modulating the cytokines, immune system
chemicals released during the immune response and necessary for
autoantibody production. Treatments of this nature are already being
used successfully in Crohn's disease.
20. I131 is so dangerous it's transported in a lead container and kept
at the hospital only for the briefest time before being dispensed by a
doctor shielded in lead from head to toe.
21. When cats are given I-131, they must be kept in a contained facility
for up to 6 weeks until they no longer set off warnings on a geiger
counter, yet people, especially in the U.S.A. are released with in
minutes of treatment on an unsuspecting population. Germany keeps I-131
patients for several days in a contained radiation facility until their
radioactive numbers are in a *safe* level. Is there REALLY anything
*safe* about ingesting I-131? (9)
22. Salivary and tear duct damage from I-131 (10)
