  1. Measurement of natural and artificial radionuclide concentrations in meat consumed in Hong Kong.

    Article - En anglais

    Radionuclides in meal are determined using the EG & G ORTEC photon spectrometer system.

    Most of the naturally occurring radionuclides are found to have specific activities below the deteclable limil.

    For our samples, 40K is found to have values ranging from 295-407 Bq/kg, 172-423 Bq/kg and 172-282 Bq/kg for beef, york and chicken meal samples, respectively, while 137Cs has values from 0. 19-2 Bq/kg, 0.34-0.71 Bq/kg and 0.12-0.53 Bq/kg, respectively.

    The estimated weighted committed dose equivalent due to the ingestion of natural radionuclides and 137Cs in meal is<0.6 mSv and 7.1 muSv for a male adult and<0.8 MSV AND 9 muSV FOR A FEMALE ADULT, RESPECTIVELY, AND THE VALUES FOR 137Cs in both sexes are less than the level recommended by the International Commission on Radiological Protection.
