Performance data

The radioactivity monitor RADEX RD1503+,

10.КР.01.00.00.000-50, evaluates radiation environment by

the magnitude of the ambient equivalent of dose rate of

gamma radiation (further - a dose rate) with taking into

account the pollution of objects by sources of beta particles or

by the magnitude of exposure dose rate of gamma radiation

(further - exposure dose rate ) with taking into account the

pollution of objects by sources of beta particles.

The device evaluates radiation environment by the

magnitude of the ambient equivalent of dose rate of gamma

radiation (further - a dose rate) with taking into account X-ray

emissions *.

Individual settings

 Two unit measures of a physical quantity: µSv/h (basic)

µRem/h (exogenous)

 Switching on/off a sound signal;

 Switching on/off a vibra signal;

 Setting a level of a signal threshold, at it's excess a

sound signal activates or vibra signal switches on;

 Calculating the value of a background dose rate;

 Displaying the value of a background dose rate;

 Displaying the difference of a dose rate between the

average indication and background;

 Animation of the pressed button (the icon of the pressed

button blinks)

* The additional characteristics are obtained as a result of

studies held by a metrology center of Ionizing Radiations of a

State scientific and metrological center «VNIIFTRI» during 1-8

December 2005 and are affirmed by the protocols dated

14.12.2005.

Range of X- radiation energy, MeV..........from 0,03 to 3,0

Range of beta-radiation energy, MeV......from 0,25 to 3,5
