Abstract: A regularization method for reconstructing the radiation coefficient problem in the diffusion equation from the terminal observation data is studied. For the terminal observations with noise data, the error estimation and convergence rate of the approximate solution of the reconstruction problem are obtained by using the polished regularization method.
