What relationship can be determined from the following information:
• The radioactive isotope iodine 131 has a half-life of 8.1 days and emits 0.8 MeV (milli-electronvolts)of energy.
• The radioactive isotope phosphorus 32 has a half-life of 14.3 days and emits 1.7 MeV of energy.
• The radioactive isotope phosphorus 33 has a half-life of 25.5 days and emits 0.25 MeV of energy.
• The radioactive isotope sulfur 35 has a half-life of 87.5 days and emits 0.2 MeV of energy.
A)The longer the half-life,the more energy emitted by the particles.
B)The longer the half-life,the less energy emitted by the particles.
C)Radioisotopes of the same element must emit the same amount of energy in their emissions and decay at the same rate.
D)Adjusted for time,radioisotopes emit the same amount of energy in their emissions.
E)Energy and half-life are not directly related.
