This study was carried out to investigate the distribution and concentration of microorganism by the method of the air contamination using RCS air sampler in underground linac room of two general hospital located in Pusan. The places of air sampling were 4 different spot in two each hopital. Therefore, total 8 places were sampled from June 30, 1996 to May30, 1997. The results obtained were as follows 1. In a agar strip GK-A media for total count of microbial particles, it was estimated to be 76 CFU/ft^(3) in ICR room, and the consulting room was 53 CFU/ft^(3), lobby was XI CFU/ft^(3), linac room was 35 CFU/ft^(3), in the M hospital, respectively. The distribution of organism in the air of M hospital were shown gram positive cocci 72%, gram negative bacilli 15%, gram positive bacilli 6.1%, fungi 6.1%, respectively . On the other hand, in P hospital, it was obtained to be ICR room 74 CFU/ft^(3), lobby- 45 CFU/ft^(3), consulting room 34 CFU/ft^(3), linac room 31 CFU/ft^(3), respectively. The distribution and concentration of microorganism in the air were detected gram positive cocci 75%, fungi 10.3%, gram negative bacilli 8.7%, gram positive bacilli 6.0%. respectively. The results were recognized to be a low frequency in the linac room. 2. In agar strip S media for total counts of M hospital, ICR room was shown the highest organism with 32 CFU/ft^(3), but the lowest organism was detected linac room with 20 CFU/ft^(3). Also, the case of P hospital was estimated high 43 CFU/ft^(3) at ICR room, low organism was shown at linac 17 CFU/ft^(3) Test of coagulase were recognized to be a negative Staphylococci 68.3% in M hospital, 60.7% in P hospital. Coagulase positive cocci was estimated to be 31.7% in M hospital, 39.3% in P hospital. 3. In agar strip C media for coliform bacteria, colony counts at ICR room 10 CFU/ft^(3), consulting room 7 CFU/ft^(3), linac room 6 CFU/ft^(3), lobby 4 CFU/ft^(3) in M hospital, respectively. On the other hand, in P hospital were shown ICR room and main lobby 7 CFU/ft^(3), consulting room 5 CFU/ft^(3), linac room 4 CFU/ft^(3), respectively.
