There are a number of etched track neutron dosimetric systems in use for personnel monitoring. In this paper the operational and dosimetric characteristics of two etching systems namely eletro-chemical etching system and chemical etching system used for personnel neutron monitoring are described. Details of the dosemeter design, processing and read out methods are given. The dosimetric characteristics of both the systems such as the back ground, dose linearity, energy response, minimum measurable dose, reporting dose and the advantages and disadvantages of the systems in routine application have been discussed.
