Nov 21 2011True smoky quartz will loose its color when heated to about 200C and the color will occur again when the crystal is irradiated with x- or gamma-rays Some (but reportedly not all) smoky quartz is sensitive to ultraviolet light and will pale when exposed to sunlight for a long time It is not as sensitive as amethyst though Using a Bruker XRF portable gold sorter you can find out in under three seconds the precious metal content in coins jewelry and other valuable items Our next generation of handheld XRF gold tester equipment enables you to not only analyze gold in a jiffy but with unprecedented precision and confidence

When they expose a particular class of artificial diamonds (namely those made from graphite that was used as neutron moderators in fission reactors) to radiation it generates a small electric field (2 volts to be exact) By encasing a chunk of radioactive material inside the diamond you create a 'battery' of sorts

Physical Properties of Graphite: - It has a sub-metallic lustre - It is opaque whereby its color ranges from Iron black to steel grey - It is very flexible - It is a good conductor Chemical Properties of Graphite: - The carbon atoms in Graphite are arranged in a hexagonal lattice - It is highly anisotropic in nature

Fluorite is considered to be one of most popular minerals in the world among gem and mineral collectors second only to quartz It is often referred to as 'the most colorful mineral in the world' owing to its variety of brilliant colors Fluorite was first described in 1530 and was originally referred to as 'fluorspar'

The Element Cobalt

Apr 08 2010(6) Cobalt-60 that I already mentioned is a radioactive isotope of cobalt but is an important source of gamma rays used to treat some forms of cancer and as a medical tracer It decays with a half-life of 5 27 years through beta-decay into nickel-60 In normal life even Co-60 really isn't dangerous to humans

CSIRO has developed a new approach to the spatial sensitivity problem to be used in conjunction with NITA which involves the use of a combination of source–detector geometries (Sowerby et al 1997a) An example of this approach is shown in Fig 1 For a transmission configuration in which the neutron source and gamma-ray detectors are placed on opposite
