Evaluation of Neutron Skyshine Contributions During Injection at an Electron Synchrotron Facility Using FLUKA

The Center for Advanced Microstructures and Devices (CAMD) is a 1.5 giga-electron volt (GeV) electron synchrotron research facility under the jurisdiction of Louisiana State University (LSU). When originally constructed in 1992, CAMD was surrounded by pasture and woodland. Over the past several years, urban development of the area has found CAMD bracketed by a shopping center, apartment complex, and business offices. These developments raised concerns amongst the CAMD radiation safety personnel regarding an increased potential for public exposure to radiation. To ensure compliance with the annual public effective dose equivalent limit of 1 milli-sievert (mSv), the radiation monitoring program was reviewed. The outside perimeter has a series of Optically Stimulated Luminescence (OSL) dosimeters that are exchanged quarterly, OSL’s with neutron detecting chips are placed inside the experimental hall and exchanged monthly, and several real-time radiation monitoring devices are located around the shield wall. Measurements from these devices and hand-held detectors have confirmed that the annual public effective dose equivalent limits are not exceeded beyond the CAMD site. However, the most well documented sources of radiation dose at CAMD all relate to the plane of the accelerator ring and emissions which occur during acceleration, beam turns, and beam dumping. Another concern is skyshine radiation, which is any radiation particle that scatters in air back to the ground. Measurements and physics suggest that the overwhelming majority of skyshine radiation originates from the two 90˚ turns leading from the underground linear accelerator tunnel up to the plane of the ring for injection. The FLUKA (FLUktuierende KAskade or Fluctuating Cascade) Monte Carlo code developed by the Italian National Institute for Nuclear Physics (INFN) and the European Organization for Nuclear Research (CERN) was selected to model CAMD radiation emissions. Through FLUKA, the particle tracks and effective dose equivalent from skyshine radiation can be simulated. The potential exposure to neighboring properties and any future construction can be estimated to complement CAMD’s existing, well-established radiation safety program

KOMPOSISI ALGA PERIFITON PADA AKAR VEGETASI MANGROVE DI DESA PANTAI HARAPAN JAYA DAN DESA PANTAI MEKAR, KABUPATEN BEKASI

Mangrove merupakan ekosistem yang paling produktif dan perifiton yang hidup menempel di akar mangrove mendominasi produksifitas primer di ekosistem tersebut dan mempunyai peran yang sangat penting dalam jaring-jaring makanan dan mengatur kandungan oksigen.Penelitian ini bertujuan untuk mengetahui komposisi alga perifitonpada substrat akar mangroveRhizopora apiculata, Avicennia marina, A. alba, A. officinalis, dan Sonneratia caseolaris. di Desa Pantai Harapan Jaya dan Desa Pantai Mekar, Kabupaten Bekasi.Pengambilan sampel alga perifiton dilakukan pada akar mangrove bagian bawah yang tergenang air laut dan dipotong ± 2 cm kemudian diawetkan dengan formalin 4%. Di laboratorium, akar mangrove disikatdalam cawan petri,sampel perifiton diambil dan diamatidibawah mikroskop menggunakan sedgewick rafter. Ditemukan 18 genus perifiton yang termasuk dalam 2 kelas yaitu kelas Bacillariophyceae dan kelas Cyanophyceaepada akar vegetasi mangrove.Jumlah genus terbanyak ditemukan pada akar Avicennia marina(15 genus). Kelimpahan perifiton tertinggi terdapat pada akar Avicennia officinalis sebanyak 2927 ind/cm2 dibandingkan dengan akar Rhizopora apiculata, Avicennia marina, Avicennia alba, dan Sonneratia caseolaris
