[en] The utilization of lactamin (pepton) and n-butyl acrylate (n-BA) as a sensitizer system for radiation vulcanized natural rubber latex (RVNRL) was studied. The concentration of 0.2 phr (parts of hundred rubber) of lactamin and 5 phr of n-BA was suitable for RVNRL. Effects of the concentrations of lactamin and irradiation doses on tensile strengths of RVNRL films were investigated. Relationships between swelling ratios and the concentrations of lactamin, the irradiation doses were determined. The swelling ratios drop sharply while irradiation doses increase with using a combination of 0.2 phr of lactamin and 5 phr of n-BA in comparison with 5 phr of only n-BA. In addition, a determination of nitrogen content of RVNRL films, which contained lactamin, was carried out after the films leached in soap water. The effect of residual nitrogen content on allergicability of the RVNRL films is negligible and permits of the industrial applications in production of health care products, such as catheters, gloves .... It was revealed that the optimum vulcanization dose of RVNRL films can reduce from 18 kGy for utilizing only 5 phr n-BA to 13 kG-V for using the combination of the 5 phr n-BA and the 0.2 phr lactamin
