**11. Health and Safety Standards in handling chemicals**

In case transporting or handling pharmaceuticals inappropriately, they can be dangerous. The trained staff are able to prevent chemical releases which can cause explosions and fire. That is why to reduce and minimize the risk and ensure more safety, Classification of Chemicals should be done by an effective way of handling hazardous chemicals. This can be done by trained and professional staff.

In addition, the Classification of Chemicals is an effective method to identify the way of how the chemicals can have harmful effects. It also helps in labeling correctly and handled in a legally manner to avoid health risks. Exploding or releasing chemicals normally can be caused by high temperature, high pressure or oxidation. This problem can be processed by lowering the oxidation work scale and understanding the right flammable limits. Certainly pharmaceutical companies have the main role to reduce these risks [6].

### **12. Practice primary laboratory safety**

In the pharmaceutical industry, basic safety has to be maintained in the laboratory as well as employees must be conscious to the basic health and safety practices and take preventive processes during work in a hazard environment. These procedures can be carried out to maintain health and safety at the laboratory such as [6]:


#### **13. Conclusion**

We can conclude that the Radionuclides which are used in nuclear medicine are considered mostly to be artificial ones. We learned that these are primarily produced in a cyclotron or a reactor. The type of radionuclide produced in a cyclotron or a reactor depends mainly on the irradiating particle, its energy, and the target nuclei. Generally, it is noted the facilities which having such equipment are limited and supply radionuclides to remote facilities that do not possess them. Nuclear medicine is the medical specialty that employs radiopharmaceuticals, has presented itself as a very useful assistant for medicine supporting in several diagnoses and treatments. The main aim of this work is to define the vital radionuclides and metal. *New Trends in Preparation, Bio Distribution, and Pharmacokinetics of Radiopharmaceuticals… DOI: http://dx.doi.org/10.5772/intechopen.101069*

At the end, this chapter aims to be useful for all whom working in nuclear medicine and to be a guide for them. It is a guide to be used to shed some lights on radiopharmaceuticals and their uses, production and safety during handling [7].
