CONPASS
Full & Inside-the-Body X-Ray Inspection System
High level of safety
In accordance with the current international radiation–safety standards, as well as with the recommendations of the National Council for Radiation Protection and Measurements of the USA (NCRP), the public, including special groups such as pregnant women and children, should not receive more than 1 mSv/year (one milliSivert = 1,000 μSv) from non–medical man originated radiation sources, without taking into account the exposure to natural radiation. The ADANI personnel inspection scanners fully comply with the international radiation–safety standards.

* Maximum permissible doses for typical medical diagnostic studies were taken from the international standard «International basic safety standards for protection against ionizing radiation and for the safety of radiation sources», Safety Series №115–1, International Atomic Energy Agency, 1994
** Typical doses for air flights were taken from the US Federal Aviation Administration (FAA) and National Research Center for Environment And Health (GSF, Germany) reports
*** Natural radiation background data were taken from FAA Radiobiology Research Team report
- Safety for the Person Being Screening
The radiation dose to be received by the person being inspected does not exceed 2 μSv per inspection. It is equivalent to a 20–minutes exposure to direct sunlight, what is lower than the dosage received during one flight. - Safety for the Screener
The scanners can be controlled by one or several screeners. The radiation dose received by screener at his working place does not exceed the natural radiation level. - Safety for the Bystanders
Exposure to radiation outside the working zone at the distance more than 2 m does not exceed the level of natural radiation and is therefore safe for bystanders.
The scanner can be placed in the compact area in crowded place (for example, near the baggage inspection scanners in the airport). - Security Technology Enabling Privacy
ADANI inspection technology protects public safety without sacrificing privacy. Digital human imaging is X–ray projection medical image and reveals any hidden objects under a person's clothing and in stomach (including concealed weapons, chemicals, prohibited objects) without body image itself.
