In this video I will be going over the main features of the Eberline 'RASCAL' portable rate meter and scalier.

• New big display with luminescent backlight. • Simultaneous indication of units of measurement, threshold level and real time on the display. • Analog ten-segment indicator of registered radiation intensity. • Possibility to perform measurements with a preset error. • Audible, vibration and vibration-audible alarm • Four-level indication of battery discharge.

• Built-in memory which allows storing up to 1200 measurements. • Mode of PC link via Bluetooth channel.

Chertezhi proektov kafe. SUBSTANCE: invention relates to determining radiation environment in the vicinity of nuclear power engineering after emergency emission of radioactive substances. Essence of the invention is that is aerial radiation area survey is carried out by means of undedicated instrument, for example, with a portable gamma radiation dose rate meter having only one onboard radiation detector. Optical radiation survey along preset route on each straight section shall be carried out twice to change height of flight. This enables to obtain data implicitly containing information on the value of attenuation of gamma radiation depending on terrain clearance. Data processing enables calculation of coefficients for conversion of the radiation levels measured at the aircraft flight elevation to terrain clearance 1 m.
