An airport is a designated area on land, water or other surface, in whole or in part, intended for take-offs, landings and above-ground aircraft traffic, including permanent structures and construction facilities contained in its boundaries, entered into the register of airports [Air Law]. In accordance with applicable legal regulations regarding civil aviation security, air transport requires both the passenger and the airport manager to meet a number of conditions determining the ability to travel on board an aircraft. This is mainly related to the limitations imposed by national and EU legal regulations. The growing threat of unlawful interference results in further consequences in the form of tighter security controls at airports. Technological development, new ways and areas conducive to greater vulnerability, have a decisive impact on the methodology and the entire process of screening people and luggage. These activities are aimed, inter alia, at detection in a luggage carried by a passenger, a prohibited item that would serve to commit a broadly understood act of unlawful interference, which in turn may be, for example, a plane crash. No wonder that the airport manager, who is burdened with the main obligation to ensure that the passenger does not have access to prohibited articles on board the aircraft, undertakes a number of organizational measures to fulfill this obligation.

The existing regulations impose the obligation to perform random cabin baggage security screening for the presence of traces of explosives (explosive trace detection, ETD) at airports. As a result, a problem arises in relation to the proper organization of security screening checkpoints and the provision of telematic devices used to facilitate the process. The study considered three options a) a dedicated ETD checkpoint, b) ETD screening in all security checkpoints, c) equipping all checkpoints with an explosive detection system (EDS). The purpose of the paper is to propose a mathematical model and conduct a practical evaluation of options concerning security checkpoint modernization in terms of the following criteria: capacity, cost, and efficiency of detecting prohibited substances. An independent evaluation was conducted on the basis of the criteria, considering the analysis of the actual inflow of baggage in individual security checkpoints and the annual costs of equipment and staff, while the efficiency of screening was subjectively evaluated by experts. The proposed mathematical model and the established calculation tool were used to evaluate the options of security checkpoint organization at Katowice Airport. As a result of the conducted analysis, option c) was recommended. This solution showed the best results in terms of capacity and efficiency and generated medium costs.

The vapour pressure of most explosives is very low. Therefore, the explosive trace detection is very difficult. To overcome the problem, concentration units can be applied. At the Institute of Optoelectronics MUT, an explosive vapour concentration and decomposition unit to operate with an optoelectronic sensor of nitrogen dioxide has been developed. This unit provides an adsorption of explosive vapours from the analysed air and then their thermal decomposition. The thermal decomposition is mainly a chemical reaction, which consists in breaking up compounds into two or more simple compounds or elements. During the heating process most explosive particles, based on nitro aromatics and alkyl nitrate, release NO2 molecules and other products of pyrolysis. In this paper, the most common methods for the NO2 detection were presented. Also, an application of the concentration and decomposition unit in the NO2 optoelectronic sensor has been discussed.
