STUDY OF EXISTING SHIELDING CHARATERISTICS OF MALAYSIAN NUCLEAR AGENCY - DENSE PLASMA FOCUS (MNA-PF) USING MONTE CARLO PHITS

Abstract

ABSTRACT
This study employs modelling tools to evaluate the effectiveness of existing shielding for the Dense Plasma Focus (DPF) neutron source at the Malaysian Nuclear Agency using the Monte Carlo simulation capabilities of the Particle and Heavy Ion Transport Code System (PHITS). Simulating the current shielding configuration, we assess its ability to attenuate neutron flux and radiation doses. The simulation results provide insights into the spatial distribution of radiation within the facility. This analysis focuses on verifying the adequacy of the existing shielding to ensure personnel safety during experiments conducted inside the room while also serving as a reference for future shielding assessments.

ABSTRAK
Kajian ini menilai keberkesanan perisai sedia ada untuk sumber neutron Fokus Plasma Padat (DPF) di Agensi Nuklear Malaysia menggunakan keupayaan simulasi Monte Carlo bagi Sistem Kod Pengangkutan Zarah dan Ion Berat (PHITS). Dengan memodelkan konfigurasi perisai semasa, kami menilai prestasinya dalam mengurangkan bilangan neutron dan dos radiasi. Hasil simulasi memberikan pandangan mengenai taburan radiasi. Analisis ini bertujuan untuk mengkaji penggunaan perisai semasa untuk memastikan keselamatan kakitangan semasa menjalankan eksperimen di dalam bilik dan digunakan sebagai rujukan untuk penilaian perisai pada masa hadapan.
