[en] Lead rubber of solid phase natural rubber has been made. It has 200 mm length. 200 mm width and 2 mm thick. The composition is 25 gram of Pb O in 100 gram natural rubber and sulfur is used as a material in the vulcanisation process. The experiment shows that the lead rubber is equivalent to Pb foil of 0,25 mm thick. Their absorption strength is 93 % for Cs 137, 36 % for Co 60 and 45 % for Na 22. The physical properties are as follows : tensile strength of 13.1 N/mm2, elongation at break 850 %, permanent set 8,3 % and hardness 32 shore A. These properties are valid for safety standard

[en] Ph-Glass Alloy for radiation protection has been melted from main component of Si02 and PbO as well as additional glass-composite material namely Na2O and K2O. The aim of this experiment is to obtain the lead glass melting process for radiation protection. The design of composition based on followed the K2O-PbO-Si02 with 3 differences kind of PbO composition: 35 %, 40 %, 45 %, while composition of Na2O and K2O is fixed at 0.7 % and 8.3 % respectively, the balance were SiO2 which was varied to meet 100 % total weight. All material was in the form of powder and was mixed evenly before they were melted down. The melting method was done on a ceramic crucible inside the conventional furnace with 4 stages: melting, fining, homogenizing and temperature controlling. During the melting process, a culet material was added as the melting catalyzer while during the fining process borax was used, and the homogenizing process will need the temperature to be stable for a certain period of time. The product of melting process was placed at the moulding graphite and was annealed at 500oC for 1 hour, for slowly cooling down purpose. The finishing touch would make a sample with a thickness of 5 mm and diameter of 30 mm. The sample will then be evaluated structure and radiation absorbability as well as the visual outlook. The result found that shows absorbability to the X-ray radiation on 70 KV was 55.6 %, 62.5 % and 74.9 % for the PbO composition of 35 %, 40 % and 45 %, respectively. In the other hand, the lead glass is homogen, where their crystal homogeneous in the lead glass, but the lead glass not clearly yet
