self from hazard of x- radiation while they are working in wards or in the Radiology Department? Introduction This research is concerned with x-radiation protection for the pediatric staff nurses while they are taken care for pediatric patient in Salmaniya Medical Complex wards and as well as in radiology department. The authors are trying to learn how the staff is exposed x-radiation exposure‚ what the risks are and what are the best methods to protect themselves from x-radiation hazard? Staff

The emission of POISONOUS GASES rather than the direct effects of lava flows or ash showers are the greatest reason for loss of life. An example is the eruption from the Laki volcano in 1783 (see first link below) in which an estimated 25% of the population of Iceland was killed. "The system erupted over an 8 month period during 1783-1784 from the Laki fissure and the adjoining Grímsvötn volcano‚ pouring out an estimated 14 km3 (3.4 cu mi) of basalt lava and clouds of poisonous hydrofluoric

Question 1: Consumer Theory 1.1: In both the Marshallian and Hicksian consumer optimisation problems‚ it is assumed that consumers are supposed to be rational. The main focus of these problems are cost minimisation and utility maximisation‚ which play a huge part in consumer demand‚ but in real life‚ these are not the only problems that are considered. Also‚ it is assumed that every consumer’s indifference curve for two goods would be the same – they are very generalised models‚ and do not take

Unit 3 P1 - Explain potential hazards and the harm that may arise from each in a health or social care setting Relating to the physical environment; If you were in a care setting e.g. Residential home‚ and the ventilation stopped working‚ or was not working as it should do. For example if some of the residents had an illness that could be passed on through air‚ then the probability is that all the residents and also staff would end up with the illness this is an acquired infection.

There are a number of reasons why some places are more at risk of experiencing a major volcanic disaster. One reason is their geographical position within the world and in relation to tectonic plate boundaries. For example you have highly destructive and explosive volcanoes often found along destructive plate boundaries because of increased pressure within the subduction zone. An example of this is the Philippines‚ which is situated above a destructive plate boundary and this leads to numerous and

With reference to two volcanic events that you have studied from contrasting areas of the world‚ compare the nature of the volcanic hazard and its impact. Mount St Helens erupted on the 18th May 1980 at 9am and is an active strata volcano Washington State USA‚ a MEDC. Where as on 18th July 1995‚ during the daytime‚ Montserrat‚ a LEDC during the day‚ Montserrat’s Soufrière Hills composite volcano of a height 1050m‚ meaning sulphur hills‚ dormant for centuries‚ erupted and produced a phreatic eruption

Hazards are anything that could cause damage to humans or buildings. Many volcanic and seismic events happen that cause hazards to humans. Often the world’s poorest people are hit the worst‚ however wealthier countries can also be adversely affected. The Kobe earthquake in Japan 1995 struck at 5.45am. Many people were asleep in bed‚ causing the hazard to be increased because the people were unaware. Although many Japanese buildings were of aseismic design‚ the roofs of their houses were designed

“The hazards presented by Tropical storms have the greatest impact on the world’s poorest people.” To what extent do you agree with this view? (40 marks) Tropical storms are defined as low pressure systems that form over tropical seas and can devastate areas of human settlements with hurricane force winds and floods. The severity of these impacts varies greatly depending on a countries development levels and is attributable to numerous factors such as: infrastructure‚ job structure‚ the provision

The natural hazards caused by plate tectonics are more a result of human factors than physical ones. Discuss to what extent do you agree with this statement? [40 marks] A natural hazard is a threat of a naturally occurring event that will have a negative effect on people or the environment. The Earth’s lithosphere (crust) is divided into tectonic plates which are constantly in motion due to the convection currents caused by heat cycles in the mantle‚ driven by radioactive decay in the Earth’s core

Plastics are synthetic substances produced by chemical reactions. Almost all plastics are made from petroleum‚ except a few experimental resins derived from corn and other organic substances. "Plastics" derived their name from their properties to be molded‚ cast‚ extruded or processed into a variety of forms‚ including solid objects‚ films and filaments. These properties arise from their molecular structure. Plastics are polymers‚ very long chain molecules that consist of subunits (monomers) linked
