In neutron method used to measure soil moisture, the source of fast neutrons is a mixture
In neutron method used to measure soil moisture, the source of fast neutrons is a mixture
Show Hint
In any neutron moisture meter, Beryllium is always the target element used to release neutrons when bombarded by alpha particles from a heavy emitter (like Radium or Americium).
This makes the presence of Beryllium key to identifying the correct answer.
