Section 335.2080  Monitoring for Contamination and Ambient Radiation Dose Rate

a)         In addition to the monitoring required by 32 Ill. Adm. Code 340, the licensee shall monitor with a radiation detection survey instrument capable of detecting dose rates over the range 1 mSv(100 mrem) per hour to 500 mSv  (50 mrem) per hour all areas where liquid radiopharmaceuticals were prepared for use or administered at the end of each day of use.  However, the licensee does not need to perform the monitoring required by this Section in areas where patients or human research subjects are confined when they cannot be released under Section 335.2110 of this Part.  The instrument shall be operable and calibrated in accordance with the requirements of 32 Ill. Adm. Code 340.510(b) and (c).

b)         At least once each week, a licensee shall measure with a radiation measurement instrument capable of measuring dose rates over the range 10mSv(1 mrem) per hour to 10 mSv (1 rem) per hour all areas where radiopharmaceuticals or radioactive wastes are stored to ensure compliance with 32 Ill. Adm. Code 340.210 and 340.310.  The instrument shall be operable and calibrated in accordance with the requirements of 32 Ill. Adm. Code 340.510(b) and (c).

c)         At least once each week, a licensee shall measure for removable contamination in all areas where unsealed radioactive materials are prepared for use, administered or stored.

d)         A licensee shall conduct the measurements required by subsections (b) and (c) of this Section in a manner that permits detection of contamination on each wipe sample of 2000 dpm per 100 square centimeters of surface area.

e)         A licensee shall retain a record of all monitoring and surveys required by this Section for 5 years.  The record shall include the monitoring date, a sketch of each area monitored, the measured dose rate at several points in each area expressed in units, multiples or subunits of sieverts or rem per hour or the removable contamination in each area expressed in units, multiples or subunits of becquerels or curies per 100 square centimeters of surface area or in disintegrations (transformations) per minute per 100 square centimeters of surface area, the manufacturer, model and serial number of the instrument used to perform the monitoring or analyze the samples and the identity of the individual who performed the monitoring.

AGENCY NOTE:  A detection instrument means an uncompensated Geiger Mueller type instrument.  A measurement instrument means an ion chamber or compensated Geiger Mueller instrument.
