Comparison of dose rate measurements between different virtual codes, real instruments, and the VRSS. Calculation codes: VRdose (Halden), Rad Pro Calculator (Beytepe), MicroShield (Lynchburg). Instruments: Berthold UMo (Vienna), RadEye G-10 (Waltham), Ribeye X-GN, RIIDEye M-G3 (Waltham), Symetrica (Southampton), Thermo FH 40 G-L10 (Waltham), and Virtual dose rate meter (Budapest).
