| 20110215255 | ASSAYING OF WASTE - A method for investigating a volume of material at an investigation location for radioactive material includes: detecting signals from a first detector caused by the interaction of one or more types of emission from the radioactive material with the first detector; detecting signals from a second detector caused by the interaction of cosmic rays and/or one or more types of particle generated by cosmic rays with the second detector; processing the signals from the first detector to provide information on the amount of radioactive material associated with the volume of material; processing the signals from the second detector to provide information on the amount of cosmic rays and/or one or more types of particle generated by cosmic rays incident on the investigation location; and correcting the information on the amount of radioactive material associated with the volume of material using the amount of cosmic rays and/or one or more types of particle generated by cosmic rays incident on the investigation location, thereby providing corrected information on the amount of radioactive material associated with the volume of material. | 09-08-2011 |
| 20100010764 | CORRECTION OF A RADIOACTIVITY MEASUREMENT USING PARTICLES FROM ATMOSPHERIC SOURCE - 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. | 01-14-2010 |
