Nuclear density meters work on the principle of measuring gamma radiation. Gamma radiation is emitted from a source. The radiation is seen by a scintillator device. The radiation is converted into flashes of light. The number of flashes of light is counted as cps. Radiation that is absorbed by the mass is not seen by the scintillator device. Therefore, the density of the media is inversely proportional to the radiation captured and seen by the scintillator or vice versa the density of the media is directly proportional to the amount of gamma rays absorbed by the media.
Our Nuclear Density and Level Meters (with Na-22 as the source) are exempted by AERB for any approvals as the Radioactivity of the device is less than 1 MBq (less than 0.027 mCurie) and we have a high resolution patented detector to work at such a low radioactivity, an algorithm not achieved yet. This instrument provides a direct value to customer/end-user as this does not
require regular audit report to be provided to radiation body by end user and also no training is required for installation and troubleshooting of the instrument.
In addition, our devices being exempted,
The user is free from any requirements of approval from radiation body for the devices,
RSO is not required in the plant and
The user is not required to send any quarterly report for the healthiness of the installed nucleonic density meters
Moreover, the device is completely safe from a health stand point of view due to the very low radiation.
The offered technology is the use in the devices of natural or artificial gamma radiation sources emitting 1 – 20 micro Curie (less than 1 mCi) which does not exceed the minimum significant activity level pursuant to the existing IAEA radiation safety standards and regulations therefore our devices are not subject to the supervision by the State Nuclear Supervision Authority, Sanitary Epidemiological Service.
In contrast to its conventional Radio-isotopic analogues, our offered devices use natural and artificial gamma radiation sources which activities do not exceed the minimum significant activity levels pursuant to the applicable IAEA radiation safety standards and regulations. Therefore, they are not subject to the supervision by the State Nuclear Supervision Authority, State Sanitary Epidemiological Supervision Authority and Ministry of Home Affairs that are confirmed by appropriate documents.
EPT offered devices are free from the main disadvantage of traditional radioisotope analogs, i.e. necessity to use a powerful radionuclide source as we have a high resolution patented detector to work at such a low radioactivity, an algorithm not achieved yet and hence the device by EPT.
Due to the absence of a radiation source or its small dimensions (there is no radiation protection) the devices of “EPT” can be mounted in the places where it is impossible to install conventional devices. The non- contact density meter do not contain moving parts and do not require maintenance . You really can “plug and forget”.
