摘要： A method for identifying and quantifying radioisotopes in a gamma spectrum. and an algorithm based on convolutional neural networks (CNN) with a direct acyclic graph (DAG) structure are provided. The capacity to capture relevant attributes of CNNs combined with the possibility of carrying out several tasks of a DAG simultaneously allows performing precise, automatic identification and quantification in a single process. After appropriate training of the network, the only input needed is the raw spectrum measured by the device, without intervention of human operators and intermediate measurement processings.

摘要： An X-ray collimator (30) that comprises:



a collimator body (31) comprising:

a collimation conduit (32) provided with an inlet (320), configured to be connected to an X-ray source (20) for the inlet of a beam (B) of X-rays, and an outlet (321), configured to emit a collimated portion (B1) of the X-ray beam (B); and
a derivation conduit (33) inclined with respect to the collimation conduit (32), wherein the derivation conduit (33) is provided with an inlet (330), configured to be connected to the X-ray source (20) for the inlet of a peripheral portion (B2) of the same X-ray beam (B) emitted by the source (20), and an outlet (331);


a reference detector (40) fixed to the collimator body (31) and provided with an inlet window (41) facing the outlet (331) of the derivation conduit (33).
