Kagan McDonald Mrs. Wilmott SAE 2nd 10/1/13 Welding Risk and Safety Precautions Welding is a really good blue collar job that pays well‚ but has its ups and downs. Welders have to deal with hazardous welding fumes that can affect their health in numerous ways. There are several different types of welding fumes and mixtures that a welder can inhale while performing a welding task. A welder’s risk of getting sick from welding depends on the different types of metals being welded and the

1. Adsorption: Concentration of liquid or gaseous molecules over the surface of a solid material is known as adsorption. It is a surface phenomenon. (e.g.) H2 adsorption over nickel. The solid material is known as adsorbent. (e.g.) Nickel‚ Silica gel‚ Charcoal‚ Zeolite The gaseous or liquid molecules are adsorbate (e.g.) H2 gas‚ Bromine‚ benzene‚ water vapour For gases‚ a special name is given as “occlusion’ 2.If the concentration is of bulk phenomenon‚ it is absorption

atom is very unstable and decays to cobalt-59. Then cobalt-59 captures a neutron and becomes cobalt-60‚ which is very unstable and decays into nickel 60. c) How does the radioisotope decay and state its half-life. Cobalt-60 undergoes radioactive decay with the emission of beta particles and strong gamma radiation. It ultimately decays to non-radioactive nickel with a half-life of 5.24 years. d) Identify those properties of the radioisotopes that make it suitable for the use outlined above. Cobalt-60
