Iran Succeeds in Producing Nuclear Thickness, Level Gauges
Iranian scientists managed to successfully manufacture nuclear thickness gauge and level gauge, and officials announced that the newly-built tools will be mass-produced in the country in the near future
Deputy Head of the Atomic Energy Organization of Iran (AEOI) for Modern Technological Applications Abdullah Solat-Sana announced the advancement on Saturday night.
He stressed that the two sensitive products were built in Iran's Nuclear Science and Technology Research Center affiliated to the AEOI.
Iran will soon introduce the two products to the market to attract investment for their industrial-scale production, he added.
The measuring principle of thickness gauge is based on the attenuation of Beta radiation emitted by a nuclear source as it passes through a material. The thickness/basis weight is determined by sensing variations in the energy radiated by the source of known intensity. The measurement is continuous On-line and therefore useful as feedback for automatic control.
Radiation gauges typically are considered when nothing else will work, or when process penetrations required by a traditional level sensor present a risk to human life, to the environment, or could do major damage to property. The liquids and bulk solids measured by nuclear gauges are among the most dangerous, highly pressurized, toxic, corrosive, explosive, and carcinogenic materials around. Because the nuclear gauge "sees" through tank walls, it can be installed and modified while the process is running--without expensive down time or chance accidental release.
Because the installation of nuclear sensors requires a Nuclear Regulatory Commission (NRC) license, associated procedures are designed to guarantee that the installation will be safe. The best way to look at the safety aspects of radioactive gauging is to compare the well defined and understood risk represented by exposing the operators to radiation against the possibly larger risk of having an unreliable or inaccurate level reading on a dangerous process.
As detectors become more sensitive and are aided by computers, radiation source sizes and the resulting radiation levels continue to drop. Therefore, the safety of these instruments is likely to continue to improve with time.
