RZBA-09D monitors manufactured by SPC Doza have successfully passed an incoming inspection at the affiliate of Rosenergoatom, JSC Balakovo Nuclear Power Plant. RZBA-09D monitors were manufactured with the use of modern lean production tools according to Rosatom Production System (RPS) principles.

RZBA-09D is a new development of the company, serial production of which has begun this year. A new type of whole body contamination monitors was developed by specialists of SPC Doza for NPPs. The monitors comply with the requirements of regulatory documents applied at the design and operation stages of nuclear power plants, as well as IEC requirements.

RZBA-09D allows you to perform a full cycle of measurements for a minimum time. They are designed to control employees leaving the area with possible contamination by alpha and beta radionuclides at nuclear power enterprises and facilities related to radioactive waste storage and processing. The monitors are very convenient in operation and their voice and visual prompts throughout the whole process of measurement allow employees of any qualification to use them.

A specialty of this new development is 24 high-sensitivity detector units of SPC Doza own production, which allow measuring the contamination of employee's whole body, including their head, sides of arms and legs.
