The record shall include the date of the survey, a sketch of each area surveyed, action levels established for each area, the measured dose rate at several points in each area expressed in millirems (microsieverts) per hour or the removable contamination in each area expressed in disintegrations per minute (becquerels) per one hundred square centimeters, the serial number and the model number of the instrument used to make the survey or analyze the samples, and the initials of the individual who performed the survey.[Eff 11/12/99] (Auth: HRS §§ 321-10, 321-11, 321-71) (Imp: HRS §§ 321-1, 321-11(21), 321-71)
