RADIOGRAPHY
Document Type and Number:
Japanese Patent JPH09178673
Kind Code:
A
Abstract:
To provide a high precise radiography suitable for a measured material having optional or large area, large capacitance three-dimensional form, in the radiography.
In a transmission type radiography, the water containing 16N of radioactive isotope is prepared in advance by irradiating circulating water 6 with neutron, and then the water containing the 16N is used as a radiation source, and made to flow near a measured material 3 through a conduit tube, and the measured material 3 is irradiated with the γ ray emitted from a γray emission part 1 accompanying with breakage of 16N, and γ ray intensity is measured with a γ ray detector 2.
