Description

TERRA-P+ is a world-known household dosimeter, designed on the basis of the professional device MKS-05 TERRA.

TERRA-P+ designed exactly for your needs if you:

– want to be sure of your radiation safety
– take care of your family
– are aware of possible radiation risks
– have a healthy diet
– own real estate or have projects under construction
– prefer active leisure time (tourism, hunting, fishing, skiing, etc.)
– like travelling
– use cash
– want to choose a useful and original gift for the loved ones
– choose the optimal price-quality ratio of the product

Purpose of use

Measurement of ambient dose equivalent rate (DER) of gamma and X-ray radiation (photon-ionizing radiation)
Measurement of ambient dose equivalent (DE) of gamma and X- ray radiation
Measurement of surface beta-particles flux density
Measurement of ambient dose equivalent accumulation time
