| titleOfInvention | Method for identifying weak gamma radioactive source under environmental background |
| abstract | The invention discloses a method for identifying a weak gamma radioactive source under an environment background, belongs to the field of weak signal identification, and aims to solve the problem that in a field environment, when the distance of a radioactive source is long, a signal of a detector is weak and is easily influenced by the environment background. The method comprises the following steps: (1) determination of background characteristic quantity R ref (ii) a (2) Actual measurement; (3) and (3) comparison: if R determined in step 2 is the background characteristic quantity R determined in step 1 ref If the gamma radiation source meets the requirement or meets the requirement within the error range, the gamma radiation source is considered to be not artificial; if R determined in step 2 is the background characteristic quantity R determined in step 1 ref If the difference is greater than a threshold, then the presence of an artificial gamma radiation source in the environment is determined. Based on the improvement of the method, the method can effectively realize the weak signal identification of the artificial gamma radiation source under the environment background, and effectively solve the problems of the method. The invention has the advantages of convenient operation, reasonable design, high experimental measurement accuracy and higher application value. |
