The Case for Personnel Radiation Monitoring by Dae In Kim

New York City Department of Health and Mental hygiene (NYCDOHMH) radiation control regulations require that personnel monitoring be performed if a worker is "likely to receive, in 1 year...doses in excess of 10 percent of the applicable limits." In addition to NYCDOHMH regulations, the International Commission on Radiological Protec- tion introduced the ALARA principle which dictates that measures should be taken by institutions to reduce radia- tion exposure of all personnel to levels As Low As Reasonably Achievable (ALARA). Monitoring with
dosimeters is a crucial component of meeting the NYC regulations and ALARA principle.

Using dosimeters properly, it is possible to accurately monitor worker exposure and develop and maintain safe work practices. EH&S issues approximately 40,000 dosimeters annually to assess workplace exposure to radiation. Two types of dosimeters are typically issued: whole body dosimeters evaluate dose to the trunk of the body and ring dosimeters estimate dose to the extremities. Fetal badges may also be assigned to declared pregnant workers who are concerned about fetal exposure to workplace radiation.  Dosimetry reports are produced either monthly or quarterly, depending on the selected dosimeter and individuals showing exposures at a level that warrants an  investigation or any    overexposure    will    be    notified    immediately    by    the    Radiation    Safety    Officer    (RSO).

It is also important for you to follow up your personal dose report. If you notice a sudden increase in your radiation dose, such as a change from 5 mrem to 50 mrem for a given quarter, or if you have any question or concern about your dosimetry records, please contact the RSO at 212-305-0303 (CUMC) or 212-854-6749 (Morningside).

Kicking the Habit at CUMC by Yvonne Wojcicki

As the enjoyable outdoor weather continues into late summer and early fall, it is important to remind the entire Columbia University Medical Center (CUMC) community that the campus wide smoke free policy remains in effect during and after work hours - and applies to everyone (faculty, staff, students and visitors). Everyone’s cooperation to promote a smoke free campus, inside and out, is needed. Launched in August 2009, the CUMC smoke-free policy prohibits smoking on all CUMC property, both indoors and outdoors. This program was developed in collaboration with New York Presbyterian Hospital to ensure a clean, safe, healthy and productive environment at CUMC, and to fully comply with New York State and City codes and regulations.
