A transformer hydrogen gas monitoring system according to an embodiment of the present invention may comprise: a sensor module, which is disposed to allow at least a part thereof to meet hydrogen gas in a transformer and measures a resistance value of a member having a variable resistance value according to a hydrogen concentration in the transformer; and a multi-task module for receiving a sensing result of the sensor module, generating hydrogen concentration information corresponding to resistance value information included in the sensing result, and remotely transmitting information corresponding to the generated hydrogen concentration information.

Transformer hydrogen gas monitoring system, device, and method

A method for detecting a radionuclide using energy spectrum data represented by a count depending on energy obtained from a radiation detector, including: calculating a count ratio for a particular energy value using a background energy spectrum data measured without a target object to detect the radionuclide and a target energy spectrum measured in the presence of the target object; and comparing a background count ratio and a target object count ratio, where the count ratio is a ratio of a low count sum of count values which is an energy value or less divided by a high count sum of the count values which is greater than the particular energy value, or a ratio of the low count sum of the count values which is smaller than the particular energy value divided by the high count sum of the count values which is the particular energy value or greater.
