  • 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 ...

  • Value addition in diamonds and other gemstones by nuclear radiation: the phobias and safety considerations

    Four Cs, namely colour, clarity, carat (weight) and cut, primarily determine the price of a gem. Neutron irradiation, gamma rays and electron beams can be used to enhance the colour and clarity of aquamarine, quartz, tourmaline, kunzite, topaz, pearls and, most importantly, diamonds. Imparting colour and clarity to these gems that are otherwise devoid of these attributes results in significant ...

  • Documented optimum and threshold for ionising radiation

    A concept of the complete dose-response curve of ionising radiation will allow us to live in harmony with this ubiquitous agent. Convincing data show ionising radiation is essential for life. Ambient levels of ionising radiation (about 2 mSv/y without medical and cosmic radiation) are adequate for life but insufficient for abundant health. We live with a partial deficiency of ionising radiation. ...
