In fact, it all started when the uranium – a type of stable isotopes were separated through the use of mass spectrometry – also known as the isotope ratio mass spectrometry (IRMS) in 1939 (Lennard, 2012; Chang, 2010; Benson et al., 2006). With the use of technology, radioactive carbon isotopes were widely used to determine the age of objects related to archeology such as fossils and other organic materials (BioZine, 2013; Chang, 2010). The two types of isotopes are known as stable and radioactive. Basically, one of the differences between these two isotopes is that radioactive isotopes are isotopes that decay over time whereas the sable isotopes do not (BioZine, 2013). In general, forensic scientists aim to identify the suspect and determine how and when a crime was committed (Benson et al., 2006). In relation to the differences between these two isotopes, this study will first discuss some basic information with regards to stable and radioactive isotopes followed by analyzing how these two isotopes can be use in the study of forensic science. Chapter 2 – Literature Review 2.1 Basic Information on Stable and Radioactive Isotopes Among the five (5) common types of stable isotopes used in the study of biological products include carbon (12C or 13C), hydrogen (1H or 2H), nitrogen (14N or 15N), oxygen (16O, 17O, or 18O), and sulphur (32S, 33S, or 34S) (BioZine, 2013; Chang, 2010; Benson et al., 2006). As explained by Benson et al. (2006), each of these elements can either be classified as a “dominant light isotope” which include 12C, 14N, 16O, 32S, and 1H or “heavy isotopes” such as 13C, 15N, 17O, 18O, 33S, 34S, and 2H. Even though most of the carbon element is considered as stable isotopes, it is necessary to take note that 14C is ...Download file to see next pagesRead More

...isotope gains dominance due to its abundant nature than the rest. Mostly, atoms are defined using their mass numbers (protons + neutrons) and this number is added to their chemical symbol as a subscript. Atom stability of the nucleus depends greatly on the protons to neutrons ratio. Isotopes have two classifications: the stable ones which do not change with time and the ones that possess a ratio that makes them unstable allowing them to change their mass numbers (Ling, et al, 2012). Stable isotopes have a constant concentration in the environment, though their distribution keeps on changing depending on the environmental preferences....

...assaults and other criminal cases. The field of forensic science needs additional research. This is because the criminals could not be convicted of their crimes without the use of science (Sidebottom, 2008). This would mean a world where murderers continue stealing and the drug traffickers persist with their illegal deals. This implies that additional research in forensic science is vital in solving crimes. Reference List Anderson, D. (2000).

EDs have psychological consequences such as problems with family and friends and low perceived happiness. Comorbidity of EDs and SUDs makes assessment, treatment, and recovery complicated than for either disorder(Courbasson, 2008). EDs are characterized by inconsistent eating patterns and negative attitudes towards food and body shape. This leads to loss of control, compulsive behavior and continuous use despite negative consequences. SUDs also have psychological effects such as poor brain function and behavior, and addiction....

..., 2007, p. 22). In effect, CSI has drawn in forensic science enthusiasts based on an inaccurate picture of the actual workings of CSI work. People have been drawn to it based on their romantic and even gallant or heroic ideals about the type of work involved in being a CSI. But this picture of the CSI in the actual practice is not all true. CSI also has had an impact on juries. Many of these juries seem to expect and even demand that the case be presented to them in much the same way as what unfolds in their TV-screens. Moreover, they seem to expect that every crime can be solved through DNA testing or through the use of the latest in technological innovations (Willing, 2004). ...

...knowledge and expertise of professionals in different disciplines can be used collaboratively to bring valid results. In trauma identification, physical anthropologists and forensic pathologists have different knowledge and expertise, though slightly related. The forensic anthropologists are trained in investigating age, sex, ancestry, and living stature of remains. They can also perform postmortem trauma identification. In as much as they can interpret trauma, forensic anthropologists are not fully responsible for the whole process. They collaboratively work with the forensic pathologists. Forensic anthropologists have...

...Toxicology s Toxicology Toxicology is a branch of forensic science, which is used to investigate deaths, poisons and drug use. In toxicology, different samples from the human body are used for testing, like bodily fluids and tissue samples. The different factors which are isolated and tested in criminal investigations, are isolated for the purpose of finding out if the victim had consumed alcohol before death, did any illegal prescription or drugs contributed towards his death, were there any other chemicals, like a poison present in the victim’s body and if there were any metals found in the toxicology, which could lead to the murderer of the victim or provide any clue with respect to its case (Whitacre, 2012). The evidence... toxicologists...
