Five Pack RadBlock 20's Coated Scored Potassium Iodide Tablets (KI)

RadBlock 20 Potassium Iodide Tablets, proudly produced by KI Canada, have been Health Canada-approved and trusted since 2003. We are official suppliers to Ontario Power Generation, Bruce Power, and the Canadian Government — organizations that depend on our products for reliable thyroid protection in nuclear preparedness programs. Each scored, coated 65 mg tablet of RadBlock 20 provides essential potassium iodide (KI) to block radioactive iodine from being absorbed by the thyroid during a nuclear or radiological emergency.

Recommended Purpose and Use:
RadBlock 20 acts as a thyroid-blocking agent for use in a nuclear emergency involving the release of radioactive iodine (radioiodine). When taken at the appropriate time and dosage, KI saturates the thyroid gland with safe, stable iodine, preventing the absorption of harmful radioactive iodine isotopes. This reduces the risk of thyroid cancer and other radiation-induced disorders. Potassium iodide is intended to complement—not replace—protective measures such as evacuation, sheltering, and avoiding contaminated food or water.

Each Tablet Contains:

• Potassium (as Potassium Iodide): 15.3 mg

• Iodine (as Potassium Iodide): 49.7 mg

• Tablet strength: 65 mg, scored and coated for easy splitting and swallowing

• Expiry date: 2034

Recommended Dosage (per Health Canada and U.S. NRC guidance):

• Adults over 40 years: 130 mg (2 x 65 mg tablets) only if exposure exceeds 500 cGy

• Adults 18–40 years: 130 mg (2 tablets)

• Pregnant or lactating women: 65 mg (1 tablet)

• Adolescents 12–18 years: 65 mg (1 tablet)

How Potassium Iodide Works:
Potassium iodide (chemical symbol KI) is a non-radioactive iodine compound that helps shield the thyroid gland from radioactive iodine exposure. When taken before or soon after exposure, KI fills the thyroid with stable iodine, reducing or preventing uptake of radioactive iodine that may be released into the air during a nuclear event. This simple but effective action helps lower the long-term risk of thyroid cancer, particularly in children and young adults, who are more sensitive to radiation.

Health Canada and FDA-Approved Protection:
Potassium iodide tablets like RadBlock 20 are approved by Health Canada and recognized by the U.S. FDA for over-the-counter use as thyroid protection during nuclear emergencies. They are inexpensive, shelf-stable, and an important component of any household or institutional emergency preparedness kit. As with all medications, individuals should consult with their healthcare provider or pharmacist before use, especially for children, pregnant women, or those with thyroid disorders.
