1. DESCRIPTION AND OPERATION OF THE PRODUCT
1.1 Application of the Product
Radioactivity detector RADEX RD1008 evaluates the radiological situation according
to the value of the ambient dose equivalent H * (10) of ionizing photon (gamma - and X-ray)
radiation (hereinafter - the dose rate), the value of the flux density of beta- radiation (hereinafter
referred to as the flux density) and acumulates the ambient dose equivalent of gamma-
radiation (hereinafter - the dose).
