  • 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 ...

  • Legionnaires’ disease (Legionella pneumophila)-sometimes deadly, sometimes not!

    More than 90% of Legionella cases are caused by Legionella pneumophila, a bacterium that thrives in warm to hot water.  Pipes, tanks, faucets, showerheads, and hot water heaters are ideal breeding grounds for L. pneumophila.  Since infection with Legionella occurs through inhaling the bacterium, any activity in which contaminated water can be misted and subsequently inhaled can lead to ...
