The present work was aimed to show the possibility of using hydrogel (acrylic/boric acid) for evaluationof the neutron radiation shielding. The influence of acrylic acid concentration, different gamma dosesand relative contents of boric acid were studied. The physical properties and the thermomechanicalstability of the studied samples were investigated. The shielding property of the composite for neutronwas tested by PueBe neutron source (5 Ci) under room temperature. The neutron fluence rates andgamma fluxes were measured using a stilbene organic scintillator. The macroscopic effective removalcross-section SR (cm 1) of fast neutrons and total attenuation coefficient m (cm 1) of gamma rays hasbeen studied experimentally. The transmission parameters, the relaxation length (??) and the half-valuelayer (HVL) were obtained. The obtained results indicated that the addition of boric acid to acrylic acidtends to increase the macroscopic effective removal cross-section SR (cm 1) to 0.141 compared to 0.094of ordinary concrete.
