Given below are wo statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: The probe of a neutron moisture meter is inserted into an access tube fixed vertically in the soil
Reason R: The probe of a neutron moisture meter contains a source of fast protons and a detector fo slow electrons and helps in estimating soil moisture content
In light of the above statements, choose the most appropriate answer from the options given below
The probe typically contains a source of neutrons (not fast protons) and a detector to measure the scattering or absorption of these neutrons by the soil. The measurement of neutron radiation helps in estimating the soil moisture content.
