  • Electrocoagulation of synthetic dairy wastewater

    This study compares the effectiveness of pollutant removal from synthetic dairy wastewater electrocoagulated by means of aluminum and iron anodic dissolution. A method based on the cubic function (third degree polynomial) was proposed for electrocoagulant dosing. Mathematical methods for calculating the optimal electrocoagulant doses proved to be quite precise and useful for practical ...

  • Physical dosimetry system in radiation accidents

    We experience various types of radiation accidents. When a radiation accident happens, one of the important aspects that we have to consider is the radiation dose to the victims of the accident. To judge the health effects due to radiation exposure, it is necessary to make a dose assessment. There is a variety of dose assessment methods, of two types: biological dosimetry and physical dosimetry. ...

  • The development of radiobiology in Bulgaria

    The ongoing changes in radiation risk assessment and development of ICRP conceptions is greatly due to the achievements of radiobiology. At doses below 0.2 Sv, radiation risk is determined only by stochastic effects. In these cases initial changes at molecular and cellular level and potentially lethal damage cannot be detected with known methods. Radiobiology and molecular epidemiology will ...
