 | The following summarizes the monitoring results on the surroundings of research reactor located at Institute of Nuclear Energy Research (INER) and, National Tsing-Hua University (NTHU), during the third quarter in 2008. Analysis numbers of sample are 189. |
| Direct radiation: |
| With thermoluminescent dosimeter (TLD), the gamma-ray exposure rates around INER were found between 0.054 and 0.079 £gSv/hr; those around NTHU were found between 0.052 and 0.068 £gSv/hr; respectively. All the data are within the variation of background environmental radiation. |
| With gamma radiation monitoring network, the gamma dose rates around INER were found between 0.052 and 0.069 £gSv/hr. All the data are within the variation of environmental background radiation. |
| Airborne particulates: |
| With gamma spectrometry, no man-made radionuclides were found. |
| Grass and Plants: |
| With gamma spectrometry, no man-made radionuclides were found. |
| Water (including drinking water, underground water, lake and river water): |
| With gamma spectrometry, no man-made radionuclides were found in underground water, lake water and river water. In tritium analysis were found between MDA and 13 Bq/L. |
| Agriculture products: |
| With gamma spectrometry, no man-made radionuclides were found. |
| Cumulative effect samples (including soil and sediment in the lakes on NTHU): |
| With gamma spectrometry, Cs-137 were found in the soil samples around INER and NTHU, between MDA and 2.0 Bq/kg.dry; Cs-137 were found between MDA and 1.0 Bq/kg.dry in the sediment sample from the Lotus and kun-Ming Pond on NTHU. |
| Based on the monitoring results on the surroundings of the National Tsing-Hua University, Institute of Nuclear Energy Research, the maximal personal dose of each location is assessed and found to be lower than the dose limit. |
