  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • 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. ...

  • Why is there no effective real-time Continuous Radiation Monitoring System?

    Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

  • Effect of 137Cs gamma radiation on the system bioindicator Tradescantia pallida

    The use of the bioindicator Tradescantia clone 4430 as a biomonitor is limited to a short period of time in regions of hot climate. This paper describes the use of Tradescantia pallida as a bioindicator, to verify its sensitivity to gamma radiation from a 137Cs source and to monitor places of low doses of ionising radiation in tropical climates. Specimens of the T. pallida were exposed to ...

  • Radiation source rate estimation through data assimilation of gamma dose rate measurements for operational nuclear emergency response systems

    This paper presents an evaluation of an innovative data assimilation method that has been recently developed in NCSR Demokritos for estimating an unknown emission rate of radionuclides in the atmosphere, with real–scale experimental data. The efficient algorithm is based on the assimilation of gamma dose rate measured data in the Lagrangian atmospheric dispersion model DIPCOT and uses variational ...

  • GOOD NEWS FOR DRINKING WATER Independent Test Lab Evaluates Instrumentation forDetecting Radiation in Drinking Water

    Since 9/11 and there are still holes in security of the nation’s infrastructure, particularly for drinking water. This security deficit is currently being addressed in some community water systems with water monitoring instruments. In the 90s the EPA developed a wish list for monitoring contaminants in drinking water. Since that time biological and chemical contaminants have been identified ...
