The scintillation nuclear radiation detector detects the alpha rays per second. When the energy of the alpha rays (Eα) in MeV increases, the number of counts (Nc) on the detector also increases linearly as shown in the table below.

Explanation
The scintillation nuclear radiation detector detects the alpha rays per second. When the energy of the alpha rays (Eα) in MeV increases, the number of counts (Nc) on the detector also increases linearly as shown in the table below.
Draw the graph of Nc as a function of Eα (MeV) and find the energy of the unknown alpha ray if the number of counts is 31600.
0.35/10000 = 0.000035
1------>0.000035
1600 ------> 1600×0.000035
1600 ------> 0.056
0,65 = 0.056 = 0.706
