Radiation Metrology for Environmental in Indonesia

Utility of nuclear technology in every field is growing rapidly. Along with the use of this technology it requires
increased safety and awareness of the impact of the utilization of this technology. One indicator to determine the increased radiation exposure is by measuring the level of radioactivity in the environment. Environmental radiation has very low levels of radioactivity with different types of radioactive and its daughter. The special problem in low level counting is that the ratios of counting rates of sample to background are often so low that significant modifications to the measurement system are needed to improve sensitivity. Various environmental radiation measurement methods have evolved with society needs security and safety against the use of nuclear technology. PTKMR-BATAN has prepared various measurement methods as well as some standard sources to conduct environmental radiation measurements accurately and have traceability to the international system of units. The measurements of environmental radiation is very useful to obtain data which can then be used to help make the correct decisions to properly care for our environment.
