其它 | Investigations of the distribution and variation of gamma radiation field play an important role in nuclear installation monitor and radioprotection. Purpose: In order to obtain the gamma radiation field distribution, one has to deal with the problem of reconstructing the whole gamma radiation field using the small scaled, discrete and irregular distributed experimental data. Methods: In present paper, several classic scattered data interpolation techniques are introduced with the emphasis on parallel radial basis function interpolation method, and the Multiquadric algorithm is applied to reconstruct the gamma field. Results: For the gamma radiation with rotational symmetry, it is found that, the reconstruction results from Multiquadric method is much better than the result from the built-in interpolation method based on the same sampling data, where the average relative error of Multiquadric result is only 9.47% of the later. |
