mal'> As required by good analysis protocol, all analytical results should state the precision of the measurement and any potential sources of error not reflected in the precision. In the absence of bias, the precision of the measurement can place bounds on which sources and processes could produce material with the given signature. Although increasing the precision of a given measurement could narrow the field of potential sources or processes that produced the material.

As it is often more efficient to perform additional measurements using independent techniques (techniques that verify the presence or absence of different signatures than those verified by the initial technique).

NUCLEAR FORENSICS LABORATORY:

The evidence should be sent for analysis to a nuclear forensics laboratory equipped to receive and process such samples. It may be possible to send the traditional forensic evidence to a police crime laboratory and the nuclear forensic evidence to a nuclear analysis laboratory. However, it is highly likely that the two types of evidence are mixed, so that the traditional forensic evidence is contaminated with radioactive material and the radioactive material contains some forensic evidence. Therefore, the receiving nuclear forensics laboratory should be able to handle radioactive material and carefully separate the traditional forensic evidence from the radioactive material for later analysis by experts in each discipline. Consequently, it is advisable to send the sample to a laboratory skilled in nuclear forensic analysis that combines the capabilities of the crime laboratory and the nuclear forensics laboratory.

Nuclear forensics laboratories should be outfitted and staffed to handle contaminated evidence and to accommodate the requirements of both the traditional forensic and nuclear analyses. The nuclear forensics laboratory needs to be appropriately licensed to receive the evidence being shipped. The receiving facility needs to be able to handle large amounts of nuclear material, yet still be able to analyse trace level of the material constituents and environmental types of material. Consequently, the nuclear forensics laboratory has to be free from fixed and dispersible background contamination to ensure that there is no chance of cross-contamination between samples.

CURRENT ARRANGEMENTS

Forensic Science is broadly divided into three parts.Medical , laboratory and field services. But these are not strictly exclusive and may overlap whenever there arises a need to do so. Also ,depending upon the nature and type of the crime and evidence collected, many forensic disciplines could be involved at the same time in detection of the crime. Field sciences generally include crime scene investigation of area like fir本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
