Abstract Objective To intruduce the principle,structure and character of a new personal neutron dosimeter.Methods In combination with relative documents,the dosimeter datum measured on neutron and γ rays emitted by 241Am-Be source,when 6LiF (Mg,Cu,P) and 7LiF (Mg,Cu,P) are disposed,are evaluated.Results Its measurement results showed good linear relationship and can be repeated.The sensitivity of neutron detection is 0.72 times of 60Co γ rays and this result is similar to that to be reported previously.Conclusion The measurement results of this dosimeter has been satisfied with the requirement of personel dose measurement in n or n-γ radiation field under 4.4 MeV energy.
