Environmental radiation hazards and role of women in family protection

People are exposed to a number of radioactive sources in their environment and daily life with different rates according to position, home surrounding, eating habits and energy sources around them. More than 85% of radiation comes always from natural sources and cannot be changed. Also, medical diagnostic and therapy, as well as handling with different types of electronic instruments e.g color T.V, computer, games, etc., include unignored part from radiation exposure. Among the family, children represent the high risk exposed group due to the relatively long time they sit infront of these instruments. The work aimed to study the radiation contamination problems on enclosed environment as well as define the role of women through family protection program. The work studied the radioactive emission of sample of 4-different electronic instruments [3 color T.Vs and one computer screen] with different model, size and production date using a portable Geiger dosemeter. Radioactive emission values on different distances infront and behined each instrument in the sample were examined [10, 20, 50, 100, 200, 250 cm]. The results revealed that values of radioactive emission are higher in behined than infront, [5 and 4 Micro Roentgen/hr on rear and front respectively at 10 cm distance] in case of color T.V. Tables. However, the emission decreased with the increase of distance [3.8 and 2 MR/hr on rear and front at 250 cm distance] for the same instrument. On the other hand, the values showed slight decrease in case of using protective shield in front of computer screen [4 and 3.8 MR/hr on without and with shield respectively], Although most of the readings are under safety permissible dose [5 rem/year] for normal population, but accumulation of doses over time could be unsafe. Eye and/or nervous system strain are expected to happen in case of long exposure time. The work recommends the introduction of scientific programs to raise community awareness against radiation hazard problems. Another recommendation is the emphasis on the role of women in family protection by directing children to deal with new technology hazards through controlling exposure time and distance. Regulating working time infront of computer screens or behind electronic instruments is, also, recommended

Evaluation of environmental engineering conditions and risk hazards in plastic recycling industry

The aim of this work was to evaluate the environmental sanitary engineering conditions, as well as, environmental risk hazards in plastic recycling industry. The results of the evaluation of environmental engineering conditions showed a good or fair score in some of the studied items. Nevertheless, reconsideration should be given to some other items. Wastewater washing analysis included higher values of oil and grease in plant A and B, and highly alkaline final effluent in plant B. Although most of air contaminants were below the recommended levels of occupational exposure, TSP, THC's and noise were high in plant B due to higher loading operations
