MARPA (Malaysian Radiation Protection Association/Persatuan Perlindungan Sinaran Malaysia) – is a non-governmental organization that was established on 15 September 2002. It represents a pool of professionals of highest skill in radiation protection and safety.

MARPA can be considered a national asset and a resource for experts and specialists in radiation protection and safety. MARPA aims at advancing scientific and technical knowledge and skill in the field of radiation through education, research and the compilation and dissemination of information useful to members and beneficial to the general public.

The establishment of MARPA also is intended to establish linkages with other technical, safety and scientific organizations in the dissemination and exchange of information to enhance the promotion, advancement and recognition of radiation safety practices in Malaysia. The idea to form MARPA was mooted in the Second RPO Conference back in 1997. Subsequently, a protem committee was formed to realize this idea. Discussions were held regularly to garner support of the would-be members. On 19 June 2002, the registration of MARPA was successfully approved by the Department of Registrar of Societies, and at the Fifth RPO Conference held in Kuching on 15 September 2002, the first AGM of MARPA was conducted and the first Members of the Council/Board were elected.

In 2006, MARPA has been accepted as the 46th member of the International Radiation Protection Association and 7th member of the Asian and Oceanic Association of Radiation Protection (AOARP).
