[en] Today, air pollution is monitored using static stations and modelling, which provides valuable information to document air pollutant levels. Nevertheless, there is still a lack of knowledge about personal exposure, especially regarding indoor air quality. Therefore, the ANR-Polluscope project (2016-2020) aims to track air pollution all day long (indoor and outdoor) by equipping volunteers with small air quality sensors in order to monitor the air we actually breathe. Target pollutants are black carbon, particulate matter (PM), NOx , ozone and VOCs. The first step of the project is to select and assess the sensors to be used, before to launch real measurements campaigns with volunteers. The results of these tests are presented here and include three testing stages. First, static measurements tests were performed to compare small sensors results with reference instruments. Then the sensors were tested into a controlled chamber in order to test their performance when environmental conditions (for instance humidity) vary suddenly. Finally, mobility tests were carried out, people wore the sensors all day long to measure the ability of the micro units to be efficient in real campaign conditions.

[en] A computer code for processing of data from neutron activation analysis is described. The code is capable of qualitative and quantitative analysis of regular spectra from neutron irradiated samples, measured by a Ge(li) detector. Multichannel analysers with 1024 channels, such as TN 1705 or a Romanian made MCA 79, and an ITC interface can be used. The code is implemented on FELIX M118 and FELIX M216 microcomputers. Spectrum processing is performed off line, after storing the data on a floppy disk. The background is assumed to be a polynomial of first, second or third degree. Qualitative analysis is performed by recursive least square, Gaussian curve fitting. The elements are identified using a polynomial relation between energy and channel, obtained by calibration with a standard sample
