Patent ID: 7786449

Claim:
An arrangement for detecting and initiating indication of doses of radiation ( 16 ), comprising: means for receiving radiation dose ( 13 a , 17 ; 13 b , 18 ; 13 c , 19 ); and means for function handling ( 20 ) for storing and displaying received radiations/radiation doses, said means for function handling being operable by one or several power sources ( 11 ), including one or several portable meters ( 1 ) exhibiting miniature external dimensions and having a power source assigned thereto, and wherein the respective meter is provided with a means for receiving radiation dose and a means for function handling of its own, wherein said meter includes one or several first components ( 22 , 23 , 24 ), requiring low power and being activated when receiving low radiation intensities, one or several temporarily connectable second components ( 29 , 30 , 31 , 32 ), requiring increased or increasing electrical power in relation to the low electrical power and including a current/voltage amplifier ( 29 ) being activated when receiving increased or higher radiation intensities, and one or several third components ( 33 ), handling a temporary connection and disconnection of the second component or components when the increased or higher radiation intensities are starting and ending, respectively.
