• The return value is 2 bytes wide unsigned activity concentration value, the unit is Bq/m3, the resolution is 1 Bq/m3, and the range from 0 to 65,534. Value 0xFFFF (i.e. 65,535) specifies a sensor error.
• FRC 2-byte: FRC return value is the activity concentration value +4 (i.e. 0x0036 = 54 is value 50). Because of FRC predefined values the raw values from 0xFFFC to 0xFFFF (i.e. 65,532 to 65,535) cannot be passed.
