Abstract: In order to timely detect the occurrence of accidental internal radionuclide contamination of workers and accurately identify the contaminated individuals for medical treatment, it was proposed to strengthen the application of nasal swab analysis in the routine monitoring programme. The reliability of nasal swab analysis for internal contamination monitoring was validated by the human respiratory tract aerosol deposition model and the real data of nasal swab analysis from nuclear facilities in the United States and Japan. All the available methods of nasal swab analysis were listed and assessed in the aspects of speed and accuracy, and the prospect of imposing a daily nasal swab analysis for internal contamination monitoring was described. To make the proposal more practicable, several specific suggestions for further research were also put forward.

Key words: nasal swab analysis, internal contamination, routine monitoring programme
