Potassium Iodide

Potassium Iodide (KI) is a protective measure which helps to protect the thyroid gland against internal uptake of radioiodines that may be released in the unlikely event of a nuclear reactor accident.

Not all nuclear power plant accident scenarios may result in a release of radioiodine requiring the distribution and use of KI. Nuclear power plants are designed to remove certain radioactive materials during an accident using filters and sprays. However, in ceratin types of accidents this may not always be possible.

The Nuclear Regulatory Commission (NRC) provided KI to states for use in the 10 mile plume phase emergency planning zone (EPZ) of commercial nuclear power stations.

VDH will recommend distribution and use of KI for members of the public at the Emergency Evacuation Centers (EAC) when the projected radiation dose to the thyroid gland exceeds 5 rem.

KI that will be made available to emergency workers and the public is shown below, followed by lot numbers and expiration dates:

ThyroSafe 65mg tablets

Lot #: TU102A, Expiration Date: 3/30/2017

Lot #: TU404A, Expiration Date: 4/30/2020

Lot #: TU405A, Expiration Date: 4/30/2020

 

9/12/14 UPDATE: IMPORTANT NOTES ABOUT EXPIRED KI

Iosat 130 mg tablets (in blister packs manufactured by: Anbex, Inc.), Lot# YXP7, expires on 09/30/2014 and can be discarded as household waste.
