Abstract

Telah dilakukan radiasi pada sampel jambu biji merah (psidium guajava linn) pada variasi dosis 0.2, 0.4, 0.6, 0.8, dan 1 kGy menggunakan sinar gamma dengan sumber isotop Co-60 serta sampel yang tidak diradiasi sebagai sampel kontrol. Penelitian ini bertujuan untuk mengetahui pengaruh radiasi sinar gamma terhadap susut bobot sebagai indikasi dari terjadinya perlambatan proses fisiologis pada buah jambu biji merah selama masa penyimpanan. Sampel jambu biji merah diradiasi sesuai dosis yang ditentukan kemudian disimpan dalam wadah plastik selama 8 hari masa penyimpanan. Hari ke 4 dan ke 8 dilakukan evaluasi terhadap massa sampel untuk mengetahui penyusutan bobot yang terjadi. Hasilnya menunjukkan bahwa sampel yang tidak diradiasi mengalami penyusutan bobot rata-rata 20.27% dan sampel yang diradiasi mengalami penyusutan bobot rata-rata sebesar 1.23 – 5.98%. Perlakuan radiasi gamma mampu memperlambat proses fisiologis dimana terjadi perlambatan penyusutan bobot pada buah jambu biji merah selama masa penyimpanan. The samples of red guava (psidium guajava linn) have been irradiated at variation doses of 0.2, 0.4, 0.6, 0.8, and 1 kGy using gamma rays with Co-60 isotope source and un-irradiated samples as control. The purpose of this research was to determine the effect of gamma irradiation on shrinkage weights as indication of slowing in physiological processes on red guava fruit during storage. Red guava fruit samples were irradiated in certain doses then saved in plastic pan during 8 days storage time. The fourth and eighth day sample mass was measured to determine the shrinkage of the weight. The result showed that un-irradiated sample was shrinkage weighted average 20.27% and the samples were irradiated shrinkage weight by an average of 1.23 to 5.98%. Gamma irradiation is able to slow the physiological processes which cause shrinkage weight on red guava fruit during storage.

Abstract

Head and neck rhabdomyosarcoma is among the most frequently encountered malignancies in children under the age of 10, necessitating effective treatment modalities with minimal toxicity. Boron Neutron Capture Therapy (BNCT) is recognized as a promising therapeutic alternative in radiotherapy owing to its ability to selectively target malignant cells. The aim of this study was to evaluate the neutron beam quality of a BNCT collimator in a simulation model for the treatment of head and neck rhabdomyosarcoma in a 10-year-old pediatric phantom, using the MCNP 6.2 Monte Carlo method. The simulation included tumor modeling incorporating Gross Tumor Volume (GTV), Clinical Target Volume (CTV), and Planning Target Volume (PTV) to assess neutron flux distribution. The results showed a thermal neutron flux of 5.22 × 10⁹ n cm⁻² s⁻¹, an epithermal neutron flux of 1.22 × 10¹⁰ n cm⁻² s⁻¹, and a fast neutron flux of 5.91 × 10⁷ n cm⁻² s⁻¹. Further analysis indicated that the produced epithermal flux exceeded the minimum standard recommended by the IAEA, and the highest flux was concentrated in the GTV region, suggesting effective tumor targeting. However, the thermal-to-epithermal neutron flux ratio (0.43) remained above the threshold value recommended by the IAEA (≤ 0.05). In conclusion, while the collimator design was capable of delivering a high-quality epithermal neutron beam that selectively targeted the tumor, further optimization of the filter components remains necessary to reduce unwanted thermal flux and enhance therapeutic safety and efficacy.
