Environmental economics. Article review 4 - Essay Example This was done by monitoring their presence in automobile filters. Furthermore, it is checked using rain water which may contain the isotopes. It has been a great worry to most researchers, scientists and writers at large. Therefore thorough checking in all possible components in the environment that can be contaminated is analyzed. Food is one such an area of major concern to these interested parties (Smith1 et al, 2014). Analysis of the samples suspected to contain heavy metals and isotopes is done using spectroscopy techniques. During analysis of the dangerous rays and substances, safety measures are taken into account to avoid accidents. For instance, shielding against cosmic rays is done. Air sampling is carried out using an air sampler to assist in determination of gamma emitting fission products from the site of occurrence. This is done with high efficiency while observing safety. Filter exchange is also done after a period of about twenty four hours. First findings indicated that Half-life of Iodine isotopes were 8 days for that with atomic number 131 and for that with atomic number of 132 took 2.3 hours. These findings were essential for establishment of a sample gamma spectrum that could give a good visual representation of findings. However, that alone is not sufficient and other sources of samples have to be considered. Therefore automobile air filters come into play. Priority is given to analysis of sample deemed to release radio isotopes that have the capability to harm or affect people. The technique aims at measuring airborne contamination degree (Smith1 et al, 2014). Samples up to about one thousand two hundreds are used to ascertain the level of available radio isotopes. They are estimated using an odometer or through monitoring of fuel consumption of the vehicles. Screening helps the researchers to get alerts of any possible contaminants. This sets the area apart and gives a
