is radioactivity a curse or a boon? By anon163055 — On Mar 26, 2011 anon162619: Check out you smoke detector, it uses trace amounts of radioactive isotope called Americium. By anon162619 — On Mar 24, 2011 how is radioactivity useful for us in our daily life? By cag238 — ...
To prevent fires or explosions, ventilating or inerting thecargo holdsand enclosed spaces near the holds is important. The ventilators must be explosion proof and the atmosphere in the holds must be monitored with a gas detector. Risks of toxic gas leakage can be mitigated by using ventilation s...
The radioactivity of a substance, or how “active” it is radioactively, is measured in either curies (Ci) or Becquerel’s (Bq). Both are measures of the number of decays per second, or how often an atom in a given sample will undergo radioactive decay and give off a particle or ph...
emission of energy from radioactivity is always accompanied by alpha, beta, and gamma particles. the rate of decay of radioactive substances is dependent on the number of atoms that are present at the time. units of radioactivity curie and rutherford are the units of radioactivity. 1c = 3.7...
What kind of materials is used in scintillation detectors? A scintillation detector consists ofa crystal or other phosphor coupled with its mount to a PM tube with a silicone oil light-couple. The oil light-couple is necessary to obtain an intimate connection of the phosphor with the photomultipl...

For a class in 2005, with no radioactive sources within range, we measured a long (30 minutes +) reading with a high-purity germanium (HPGe) gamma-ray detector system. We then identified the source of each peak. The spectrum is shown in the figure. Click it for the identifications. HPG...
2.1. Ionization Smoke Detector Ionization Smoke detector generally contains two chambers. The first is used as a reference to compensate for changes in ambient temperature, humidity or pressure. The second chamber contains a radioactive source, usually alpha particle, which ionizes the air passing th...
Deuterium is a non-radioactive isotope of hydrogen where high energy is stored in the bond between proton and neutron. In water, deuterium will undergo the nuclear fusion reaction process that is accompanied with the release of energy (nuclear energy). Deuterium release energy in millions of ...
A fiber-optic-based profiler is an instrument whose detection probe and detector data analyzer are located remotely from each other but connected by a fiber optic cable.The use of these cables provides zero signal attenuation, so engineers can measure the roughness of surfaces that cannot be reach...
