Abstract: Physical structure and activities undertaken at green spaces provide substantial health, social, environmental, psychological, and economic benefits to residents of an urban area. Study regarding the health benefits of green spaces in developing countries is very limited. Addis Ababa is the capital and the largest city in Ethiopia and not many studies on green spaces are available. Thus, this community-based cross-sectional study was conducted among 204 residents of Addis Ababa city. A multistage sampling technique was used, the sample size was allocated proportionally and selected by a simple random sampling technique. Data were coded and entered into Epi Info ™ 7 and exported to SPSS version 25 for cleaning and analysis. Results showed that only 30% of the respondents visited green spaces in the last 12 months. The common reasons for the visit were to adore nature (30.4%), refresh mind (25%), and “breathe quality air” (20.6%). Although most study participants were aware of the appealing psychological benefits of green spaces, only 55.9% of them had a positive perception regarding the health benefits of green spaces. Compared with the negative perception those with positive perception were more than twice more likely to visit green spaces (AOR: 2.51; 95% CI: 1.33-4.77). The study concluded that in addition to expanding the green spaces efforts have to be directed to solving challenges that discourage visits, increasing awareness, and improving the perception of the community regarding added health benefits of green spaces.

Abstract: Inshas site is very important site, it is considered as a first nuclear site in Egypt. It contains the first and the second research reactors and other important facilities such as the Egyptian Fuel Manufacturing Pilot Plant (FMPP) which submits the fuel to the second research reactors. The goals of this paper are to assess different emergency plan scenarios, determine the effects of metrological conditions on the dispersion of the radioactive plume, and calculate the overall effective dose equivalent values (TEDE). The meteorological parameters for one complete year 2020 (hourly) meteorological data were analysed in details such as wind direction, wind speed and temperature. The HotSpot code was used to model atmospheric dispersion and its application resulted in a radiation dose profile around the site using meteorological parameters specific to the area under study. This study used more than one scenario to investigate the role of various meteorological parameters. The radionuclide source term of Cs-137 was assumed to be 2.10E+15Bq. The results show that the maximum dose form all postulated scenarios is about 1.1E+4 Sv is observed at 10 m from the release source for weather stability class F, which is greater than the IAEA occupational exposure limit of 0.02 Sv per year. The results can also show that the time of accident is a major effect on the impact of accident and then on the consequences of emergency plan.
