An integrated circuit includes a sensing module, a measuring module, a comparing module, and memory. The sensing module senses radiation incident on the integrated circuit. The measuring module communicates with the sensing module and measures an amount of the radiation incident on the integrated circuit. The comparing module communicates with the measuring module and compares the amount of the radiation to a predetermined threshold and generates an indication that the amount of the radiation is less than the predetermined threshold or that the amount of the radiation is greater than or equal to the predetermined threshold. The memory stores the indication.
