摘要:
A method of correcting a measure of radioactive material within a body of material includes measuring a characteristic of the radioactive material to provide a measure, such as gamma emissions; detecting muons and/or electrons generated by muons which have not passed through the body of material to give a first value; detecting muons and/or electrons generated by muons which have passed through the body of material to give a second value; processing the first value and second value to give a factor, for instance indicative of the density of the body of material; and correcting the measure using the factor to obtain a corrected measure of the radioactive material with the body of material, for instance to correct for the density of the body of material and attendant issues such as attenuation and shielding.
