34-67 EFECTUL BIO-FITO-MODULATORILOR ANCU DINCĂ CA METODĂ DE REDUCEREA A CO2 DIN AER

THE EFFECT OF BIO-PHYTO MODULATORS ANCU DINCĂ AS A METHOD FOR REDUCING CO2 IN AIR
Air pollution is a major problem nowadays, with consequences for human health as well as increasing the „greenhouse effect”. The level of CO2 concentration is worrying. A simple method for stimulation plant photosynthesis is provided by bio-fito-modulators Ancu Dincă type of DIEE and DEA. The changes of dry mass during the photosynthesis process that occurred in the Paulownia species were tracked using AncuDincă bio-phyto-modulators attached to the strain of the plants. The results of the experiments presented in this article confirm the beneficial contribution of Bi-phyto-modulators AncuDincă to the process of photosynthesis. The use of these devices can be recommended as a simple and cost-effective, environmentally friendly method for reducing CO2 in indoor air by choosing the right plants.

32-95 METODOLOGIA DE DETERMINARE PASIVĂ A CONCENTRAȚIILOR DE RADON ÎN AERUL DIN INTERIORUL CLĂDIRILOR

THE METHODOLOGY TO PASSIVE MONITORING OF INDOOR RADON IN BUILDINGS
Radon inside buildings represents the main source of human exposure to ionizing radiation in the world. Studies in many countries have shown that high levels of indoor radon increases the risk of lung cancer. This article present the method selected by the competence European authorities as the most suitable to complete the map of indoor radon concentration in buildings. The 59/2013 EURATOM Directive recommends to all European member countries to implement their legislation in order to protect the population from radon since 2018. The recommended method for measuring the annual concentration of radon in buildings is based on passive monitoring of radon levels by CR-39 radon detectors.

32-94 METODOLOGIE PENTRU MĂSURĂTORILE DE RADON DIN SOL

THE METHODOLOGY TO PERFORM SOIL-RADON MEASUREMENTS
Exposure to radon in homes and at workplaces constitutes one of the greatest risk from ionizing radiation. The main source of radon in buildings can be consider the soil around the house. Radon constitutes a risk which can be managed and can be reduced at reasonable costs, thereby saving many lives. The harmonized method most used worldwide to evaluate the risck of radon at a building site is presented in the curent paper.
Keywords: radon, sol, permeabilty
