Preliminary Investigation on The Patient and Occupational Doses in Interventional Procedures in Indonesia

The medical use of ionizing radiation is known to offer great benefit to patients, yet contribute significantly to radiation
exposure of individuals and populations. According to UNSCEAR, the increase of medical examination procedures involving
fluoroscopic and interventional radiology resulted in both modalities become the biggest contribution to the radiation doses
received by population. This study attempts to investigate the patient and occupational doses in interventional procedures in
Indonesia. Patient doses were estimated by using individually packed three TLD-100 chips attached in the x-ray tube, while
occupational doses were measured also by using individually packed three chips of TLD-100 placed in over- and under-thyroid
shield used by medical staff, over- and under-apron in waist position, inside a special ‘eye-D’ holder, and inside a ring holder. All TLDs were calibrated in the Secondary Standard Dosimetry Laboratory (SSDL) Jakarta. The results show that coiling
procedure in interventional radiology produced the highest dose to patient compared with other procedures, while in
interventional cardiology, the patient received the highest dose when undergoing catheterization followed by stenting procedure.
In the case of occupational exposure, the.medical staff received the highest dose when conducting the coiling procedure and
catheter followed by stenting procedure in interventional radiology and interventional cardiology, respectively. The results of
measurement were also in good agreement with some other published data.
