Radiation dose assessment at amang processing plants in Malaysia
Measurements of external radiation level, radon/thoron daughters concentrations in air and uranium/thorium concentrations in airborne mineral dust at 16 amang plants in Malaysia were carried out for three consecutive months to assess radiation dose to workers. Estimated occupational dose was within the range of 1.7-10.9 mSv y(-1).

Radiological impacts of the amang processing industry
In 1991, the Atomic Energy Licensing Board of Malaysia (AELB) reported results from a survey conducted on 29 amang plants. Using data from inhalation of airborne radioactive dust, radon and thoron progeny, and external radiation, the AELB concluded that the total dose received by workers were in excess of 5 mSv (AELB, 1991).
