Abstract: NEUTRON QUALITY FACTOR AND DOSE EQUIVALENT Chen Changmao Liu Jinhua Liu Dijin（China Institute of Atomic Energy,Beijing 102413）ABSTRACT The development on the concept of neutron quality factor and dose equivalent is briefly introduced. An empirical formula on effective neutron quality factors recommended bv the ICRP report 60is given. The fluence to ambient dose equivalent conversion coefficients for some monoenergic neutrons are given as well.Key words neutron quality factor dose equivalent empirical formula conversion coefficient
