BATAN mengembangkan iradiator gamma kategori IV bekerjasama dengan IZOTOP (Hungaria). Teknologi transportasi produk yang akan dikembangkan menggunakan sistem rel dengan rantai sebagai penariknya. Produk yang akan diiradiasi dimasukkan ke dalam tote kemudian ditempatkan pada lintasan transportasi, ketika tote telah berada di ruang iradiasi tote tersebut akan masuk ke dalam rak iradiasi. Pergerakan tote selama di rak iradiasi akan digerakan oleh sistem pneumatik. Berdasarkan data, terdapat 14 silinder pneumatik yang terdapat pada ruang iradiasi. Melalui hasil analisis maka digunakan pneumatik silinder kerja ganda yang berasal dari katalog pneumatik Festo. Hasil perhitungan menunjukan bahwa gaya yang digunakan pada semua jenis silinder untuk memindahkan tote masih jauh lebih kecil dari gaya bengkok yang diizinkan. Selain itu terdapat 4 kelompok pneumatik yang memiliki kesamaan spesifikasi yaitu kelompok satu silinder C1, C3, C12 dan C14 kelompok dua yaitu silinder C2, C4, C11, dan C13 kelompok tiga yaitu silinder C7, C9, C15 dan C17 dan kelompok empat yaitu silinder C10 dan C17.

BATAN develops iradiator gamma category IV incooperation with IZOTOP (Hungari). Transportation technology products that will be developed uses rail system to pool. Products that will be irradiated are put into tote then placed on the transportation rail, when tote has been in irradiated room tote enters into irradiated rack. The movement of the tote during on irradiated rack will be driven by the pneumatic system. Based on data from Izotop there are 14 cylindrical pneumatics that are in the irradiated room. Through the results analysis then used double acting silinder type from the Festo pneumatics catalog. Through the results calculation that the force used on all types of cylinders for movement tote still much smaller than of force bent permitted. Beside that there are 4 group a pneumatic have common specifications they are group one cylindrical C1, C3, C12 and C14 they are group two cylindrical C2, C4, C11, and C13 they are group three cylindrical C7, C9, C15 and C17 they are group four cylindrical C10 and C17.

[ABSTRAK
Latar belakang : Salah satu reaksi transfusi lambat yang bersifat fatal adalah TA GVHD (Transfusion Associated Graft Versus Host Disease). Kejadian TA GVHD pada pasien immunocompromised diperkirakan sebesar 0,1- 1,0% dengan angka kematian sekitar 80- 90%.7 Upaya radiasi komponen darah seluler saat ini merupakan cara yang paling efisien dan dapat diandalkan untuk mencegah TA-GVHD. Penelitian ini bertujuan untuk mengetahui pengaruh efek berbagai dosis radiasi terhadap sel darah merah selama penyimpanan. Metodologi : Penelitian ini menggunakan desain deskriptif analitik pada 72 sediaan sel darah merah yang memenuhi kriteria inklusi dan eksklusi. Sediaan sel darah merah dibagi menjadi 4 grup, yaitu grup yang mendapat dosis 2500,3000,5000 cGy dan kontrol. Dilakukan pengujian OFT dan kadar kalium pada hari pertama, ketiga dan kelima penyimpanan. Hasil : Terjadi peningkatan kadar kalium yang bermakna secara statistik mulai dari hari pertama setelah dilakukan radiasi pada semua dosis. Tidak ditemukan perbedaan bermakna ketahanan membran sel darah merah terhadap semua dosis radiasi selama penyimpanan sampai hari kelima. Simpulan : Radiasi pada dosis 2500-5000 cGy dapat menyebabkan peningkatan kadarkalium dan tidak menyebabkan perubahan fragilitas sel darah merah yang disimpan selama 5 hari setelah radiasi. Perlunya penelitian lebih lanjut mengenai mutu sediaan sel darah merah selama penyimpanan setelah dilakukan radiasi seperti melihat tingkat hemolisis (hemolisis rate).

ABSTRACT
Background: One of the delayed transfusion reactions that are fatal is TA GVHD (Transfusion Associated Graft Versus Host Disease). TA incidence of GVHD in immunocompromised patients is estimated at 0.1 to 1.0% with a mortality rate of approximately 80-90% .7 Efforts irradiation of cellular blood components is currently the most efficient way and a reliable way to prevent TA-GVHD. This study aims to determine the effect of various doses of irradiation effects on red blood cells during storage. Method: This study used a descriptive analytic design at 72 red blood cell preparations that meet the inclusion and exclusion criteria. The preparation of red blood cells were divided into 4 groups, ie the group that received 2500,3000,5000 cGy dose and control. OFT testing and potassium levels on the first day, the third and fifth storage. Results: An increase in potassium levels was statistically significant from the first day after irradiation at all doses. Found no significant differences in red blood cell membrane resistance to all doses of irradiation during storage until the fifth day. Conclusion: Irradiation at doses of 2500-5000 cGy can cause increased pottasium level and does not cause changes fragility of red blood cells stored for 5 days after irradiation. The need for further research on the quality of the preparation of red blood cells during storage after irradiation as seen levels of hemolysis (hemolysis rate).;Background: One of the delayed transfusion reactions that are fatal is TA GVHD (Transfusion Associated Graft Versus Host Disease).
