The reference book contains characteristics, designs, connection diagrams of gas-discharge, scintillation, semiconductor detectors and ionization chambers used in ship dosimetry equipment, as well as recommendations on the choice of their operating modes. The considerable amount of information presented in the form of tables and graphs makes the book useful not only for specialists involved in the design and operation of ship dosimetric equipment, but also for scientists, students and graduate students who are in contact with similar problems in other fields of knowledge.
