Measurement of 238U, 232Th, 87Rb, and 40K in honey by ICP-mass spectrometry

الملخص EN

The elemental concentrations of U, Th, Rb and K were measured in some honey samples of different origins by ICP-mass spectrometry.

The samples were collected from local markets and producers in Riyadh city.

The activity concentrations of the main radioisotopes of known natural abundance, 238U, 232Th, 87Rb, and 40K were calculated using mass-activity relationship.

For quality control, the technique was tested against standard reference materials.

The results showed that the activity levels are mainly related to 40K.
