Device including an α-ray source and an electronic circuit influenced by α-ray

A device comprising:

• an α-ray source;
• an electronic circuit influenced by α-ray;
• and
• an organic layer including an α-ray shielding agent,
• wherein an α-ray shielding ability X of the α-ray shielding agent, which is calculated by the following method, is 0.50 or less,
• the method of calculating the α-ray shielding ability X:
• a laminate having a glass substrate and a layer which is composed of the α-ray shielding agent and is disposed on a surface of the glass substrate, and a glass substrate on which no layer being composed of the α-ray shielding agent is disposed are prepared, an amount A1 of α-ray in the laminate on the side of the layer being composed of the α-ray shielding agent and an amount A0 of α-ray in the glass substrate on which no layer being composed of the α-ray shielding agent is disposed are calculated using an α-ray measuring device, and the α-ray shielding ability X which is a ratio of the amount A1 of α-ray to the amount A0 of α-ray is calculated, and
• wherein the electronic circuit is one selected from the group consisting of a logic circuit, a storage circuit, and a communication circuit, and
• the device functions as an electronic module.
