  1. RadBlock 200 Potassium Iodide Tablets are Health Canada-approved and trusted by Ontario Power Generation, Bruce Power, and the Canadian Government since 2003. Each scored, coated 65 mg tablet provides the best value for protecting the thyroid during a nuclear or radiological emergency. RadBlock is a potassium iodide (KI) supplement designed to block radioactive iodine from being absorbed by the thyroid gland — reducing the risk of thyroid cancer and other diseases caused by exposure to radioiodine.

    Recommended Purpose and Use:
    RadBlock acts as a thyroid blocking agent during a nuclear emergency involving the release of radioactive iodine. It should be taken in addition to safety measures such as evacuation, sheltering, and avoiding contaminated food or water. When taken at the proper dosage and time, potassium iodide saturates the thyroid with stable iodine, preventing the uptake of harmful radioactive iodine.

    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.

    • Expiry: 2034

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

    • Adults over 40 years: 130 mg (2 tablets of 65 mg) only if exposure >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).

    • Children 3–12 years: 32 mg (½ tablet).

    • Infants 1 month–3 years: 32 mg (½ tablet).

    • Birth to 1 month: 16 mg (¼ tablet).

    How Potassium Iodide Works:
    Potassium iodide (chemical symbol KI) is a stable form of iodine — similar to table salt — that helps prevent the thyroid gland from absorbing radioactive iodine during a nuclear event. By filling the thyroid with safe, non-radioactive iodine, KI prevents radioactive isotopes from accumulating and causing long-term thyroid damage or cancer.

    When to Take KI:
    Potassium iodide should only be taken when instructed by public health authorities or emergency management agencies. It provides temporary protection for about 24 hours per dose and is most effective when taken shortly before or soon after exposure to radioactive iodine.

    Safety and Availability:
    RadBlock 200 is an over-the-counter medication approved by Health Canada and recognized by the U.S. FDA. It is a safe, inexpensive, and effective addition to your emergency preparedness kit. Always consult your healthcare professional before taking any medication. Keep RadBlock in a cool, dry place and out of reach of children.

    About Ionizing Radiation and Protection:
    Nuclear power plants and radiological events can release isotopes such as iodine-131 (I-131), cesium-134, and cesium-137. I-131 accumulates in the thyroid, particularly in children and adolescents, increasing the risk of thyroid disorders. Taking KI helps block radioactive iodine but does not protect against other radioactive materials. It should be combined with evacuation, sheltering, and decontamination procedures.

    Who Should Have KI Tablets:
    Public health agencies recommend keeping potassium iodide tablets available for families living within 100 km of nuclear facilities, first responders, and anyone preparing for emergency scenarios involving radiation exposure.
