Abstract
Telah dilakukan analisis kadar tritium pada airtanah di beberapa lokasi di Semarang menggunakan pencacah kelip cair (Liquid Scintillation Counter) PACKARD 2000 CA/LL. Sebelum pencacahan, cuplikan airtanah diperkaya lebih dahulu dengan benzene synthesizer Task Inc., USA. Dari percobaan diperolefa hasil optimum pada perbandingan cuplikan airtanah dan pengelip (pico fluor) 10:10. Kadar tritium hanya terdeteksi pada daerah Manyaran dan Semarang kota dengan hasil masing-masing 33,80 ± 7,1.5 TU dan 28,39 ± 8,78 TU. Data tersebut memperlihatkan bahwa airtanah di Manyaran lebih muda dibanding airtanah di Semarang kota. The analysis of natural tritium contents in groundwater of Semarang regency has been done. The analysis was carried out with LSC PACKARD 2000 CA/LL and enrichment using benzene .synthesizer Task Inc., USA for sample pretreatment. The optimal condition could be achieved if a pico flour scintillator used with the volume ratio of samples H2O and pico flour is 10:10. Results shows that the activity of Manyaran area is 33.80 ± 7.15 l'U and Semarang center is 28.39 ± 8.78 TJJ, so the age groundwater of Manyaran area is younger than Semarang center.
