Potassium iodide protects against radioactive iodine accumulating in the thyroid. It's most effective within 24 hours of exposure and does not protect against any other radioactive element.

There are two types of DTPA - calcium (Ca-DTPA) and zinc (Zn-DTPA). Ca-DTPA is more effective within 24 hours of exposure, but they're equally effective after that. It's only effective with plutonium, americium, and curium. For most exposure, it's an IV, but for inhaled nuclear material it can be a mist. Both of them will also bind to zinc, manganese, and magnesium (Ca-DTPA more aggressively than Zn-DTPA), so dietary supplements may be needed to prevent malnutrition. Because they're equally effective after 24 hours and Ca-DTPA is more toxic, the recommended strategy is to dose with Ca-DTPA for the first day and Zn-DTPA afterward. Chelation therapy can last for years, and while real-world effectiveness varies widely, for game purposes it can be considered to allow the user to excrete in urine about 25 times as much radioactive material as normal (this is roughly its real-world americium effect).

Prussian blue is now primarily taken orally as 500mg capsules and binds cesium and thallium. The material is excreted in bowel movements. It reduces the biological half-life of cesium from 110 days to 30 days and thallium from 8 days to 3 days.

In 2015, a new drug was approved, Neupogen, which stimulates white blood cell production. It's expected that it will help accelerate the recovery of the immune system when radiation damages bone marrow and slows the production of blood cells. It's an injection given daily for up to two weeks, and is recommended for those who receive a dose of 2 Gray or more in a short period of time at a dose of 10 micrograms per kilogram of body mass. It doesn't chelate any heavy metals, so it would be best used in conjunction with other treatments. It can cause damage to the spleen and blood vessels, so it's a bit more aggressive of a treatment than the others.
