What is the half-life of AU 198?
2.697 days
How do you calculate the half-life of sodium 24?
Notice that the time period between each of the yellow crosses is 15 hours. This tells us that the count rate of Sodium-24 halves every 15 hours. In other words, the activity of Sodium-24 is halved every 15 hours. We can summarise this by saying that Sodium-24 has a half-life of 15 hours.
What is the half-life of iodine 123?
13 hours
Why is iodine-123 better than iodine 131?
Total body imaging with I-123 was more sensitive than I-131 TBI scanning for detecting residual or recurrent disease in patients with well-differentiated thyroid cancer presenting with low preoperative thyroglobulin levels.
What are the side effects of radio active iodine?
Some side effects from radioactive iodine treatment include:
- Metallic taste in your mouth.
- Dry mouth.
- Sore throat.
- Neck pain.
- Nausea or vomiting, which is usually mild.
- Constipation or diarrhea.
- Fatigue.
- Unusually low (hypothyroidism) or unusually high (hyperthyroidism) thyroid levels.
What is the difference between iodine-123 and iodine 131?
Iodine, in the form of iodide, is made into two radioactive isotopes that are commonly used in patients with thyroid diseases: I-123 (harmless to thyroid cells) and I-131 (destroys thyroid cells. RAI is safe to use in individuals who have had allergic reactions to seafood or X-ray contrast agents.
Why is iodine 131 not suitable as a tracer in the body?
Radiotoxicity of iodine 131 Ingested Iodine-131 is dangerous because it primarily affects the thyroid gland that plays a fundamental role in childhood development. Radioactive iodine toxicity varies greatly with age, with toddlers, young children and adolescents being far more sensitive than adults.
Does iodine help lose weight?
Using an iodine supplement, you can stimulate thyroid hormones and boost immune system function because of its anti-bacterial effects on the human body. With a properly working thyroid, many people experience weight loss naturally just by increasing their iodine intake.
How long do you have to be in isolation after radioactive iodine?
You should sleep alone for the first 3 to 5 nights after treatment. Avoid personal contact for about 3 to 7 days after treatment. In those first 3 days after therapy, you should stay a safe distance away from others (6 feet away, approximately).
