4.3 Individuals with a known or suspected iodine allergy are to be provided with a substitute thyroid blocking agent.
4.4 Substitute agents are also to be issued to individuals exhibiting side effects of potassium iodine. These effects include skin rash, swelling of salivary glands, n\ettalic taste with possible burning in mouth or throat,sore teeth and gums, symptoms of head cold, stomach upset. and diarrhea, and allergic reactions with fever and joint pains. These side effects may not be evident until 10 days on continuous use.
5.0 PROCEDURE 5.1 Sampling 5.1.1 Disassemble sample head.
5.1. 2 Clearly mark an arrow on cartridge in direction of air flow.

Tablets should be taken at the rate of one tablet per day for a maximum of 10 (ten) consecutive days.
5.3.3 .Substitute blocking agents will be available from the Health Physicist who maintains records of individuals with known or suspected iodine allergies.
Substitute agents may vary based on need, availability and physician's advice.
