Abstract

PENGUKURAN KONSENTRASI RADIOAKTIVITAS UDARA LINGKUNGAN DI KAWASAN PUSAT PENELITIAN TENAGA NUKLIR (PPTN) PASAR JUMAT, JAKARTA. Pengukuran tingkat radioaktivitas udara lingkungan di kawasan PPTN Pasar Jumat telah dilakukan dengan mengambil sampel di II titik dalam kawasan yaitu 3 titik di kawasan Pusat Pendidikan dan Pelatihan (PUSDIKLAT), 3 titik di kawasan Pusat Pengembangan Bahan Galian dan Geologi Nuklir (P2BGGN), 2 titik di kawasan Pusat Penelitian dan Pengembangan Keselamatan Radiasi dan Biomedika Nuklir (P3KRBiN) dan 3 titik di kawasan Pusat Penelitian dan Pengembangan Teknologi Isotop dan Radiasi (P3TIR). Dalam perhitungan konsentrasi radioaktivitas udara (KRU) ini dipertimbangkan parameter waktu paro radionuklida dan koreksi faktor geometri pencacahan sampel terhadap sumber standard Ra.D.E.F Partikulat udara dikumpulkan dengan kertas filter menggunakan air sampler dan dicacah menggunakan alat pencacah Geiger Mueller. Berdasarkan perhitungan yang dilakukan diperoleh tingkat KRU tertinggi di ruang lim bah (P3KRBiN) yaitu sebesar 1,56502 Bqlliter, sedangkan KRU terendah di halaman belakang SDAL (P3TIR) yaitu sebesar 4,52441 x 10-3 Bqlliter. Tingkat KRU yang lain berturutturut adalah 9,7231 x 10-3 Bq/liter (ruang kelas A-Pusdiklat), 9,2174 x 10-2 Bqlliter (bunker . penyimpanan sumber-Pusdiklat), 7,19356 x 10-2 Bqlliter (di atas bunker penyimpanan sumber- Pusdiklat), 6,01847 x 10-3 Bqlliter (depanpintu masukgedung Pusdiklat), 4,89352 x 10-3 Bqlliter (tempat penyimpanan limbah cair-P2BGGN), 5,85681 x 10-3 Bqlliter (pembuangan udara Lab Geokimia-P2BGGN), 2,7457 x 10-' Bqlliter (ruang pengerusan Lab. Geokimia-P2BGGN), 1,58613 x to' Bq/liter (taman-P3KRBiN), 5,36863 x 10-3 Bqlliter (depan pintu penyimpanan limbah-P3TIR) dan 4,93260 x 10-3 Bqlliter (menara air-P3TIR) (MEASUREMENT OF THE ENVIRONMENTAL RADIOACTIVITY LEVEL IN THE AIR AT PASAR JUMAT NUCLEAR RESEARCH CENTRE AREA. Level of radioactivity in the air was measured from samples at 11 locations in the Nuclear Research Centre Area; namely 3 locations at Centre for Education and Training (CET) area, 3 locations at Centre for Development of Nuclear Ore and Geology (CDNOG) area, 2 points at Centre for Development of Isotopes and Radiation Technology (CDIRT) area and 3 locations at Centre for Development of Radiation Safety and Nuclear Bio-medicine (CDRSNB) area. In the calculation of radioactivity concentration in the air (derived air concentrations - DAC), it is considered radionuclide half life and geometric factor on the counting. Air particulates are collected in the filter by using air sampler. Then it's activity is measured by GM counter. Based on the measurement, the location at waste room (CDRSNB) has the highest DAC, as 1.56502 Bq/liter. Meanwhile, the location at backyard SDAL (CDIRT) has the lowest DAC, as 4.52441 x 10-3 Bq/liter. The other DACs subsequently, are 9.7231 x 10-3 Bq/liter (class room A-CET)), 9.2174 x 10-2 Bqlliter (bunker CET), 7.19356 x 10-2 Bqlliter (above bunker-CET), 6.01847 x 10-3 Bqlliter rt,ont of entry door- CET), 4.89352 x 10-3 Bqlliter (liquid waste room-CDNOG), 5.85681 x 10- Bqlliter (air outlet Geochemicallab-CDNOG), 2.7457 x 10-' Bqlliter (Geochemicallab-CDNOG), 1.58613 x 10-2 Bqlliter (park-CDRSNB), 5.36863 x 10-3 Bqlliter (front of radioactive waste storage-CDIRT) and 4,9326 x 10-3 Bqlliter (water tower-CDIRT).)
