Americium-241 undergoes fission to produce three neutrons per fission event. a change occurred that caused the rate of fission to increase. what will be effective at achieving a critial mass is "Remove a deflective shield surrounding the sample."Option A. This is further explained below.
<h3>What is
Americium-241 ?</h3>
Generally, Americium-241 is simply defined as a radioactive isotope. Chemical symbol Am stands for a man-made radioactive metal that is solid at room temperature.
In conclusion, The fission of Americium-241 produces three neutrons each time. The rate of fission increased as a result of a modification. removing a deflective barrier around the sample will be beneficial in reaching a critial mass.

Answer:
Carbon-14 dating, also called radiocarbon dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14). Carbon -14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic.
