The characteristics of the radiations highly depend on the temperatures on the material. One of the main features of radiation relates to the fact that radiation takes places place at diverse frequencies. This is even at a single temperature In this case, Plank’s radiation law shows how much radiation is released at each frequency. The other feature relates to the fact that as the temperatures increase, so do the frequencies and this directly relates to the range of radiation emitted from a material. The third feature of radiation entails the relationship between radiation and temperature increase. (Watts, 2003)In this case, as temperatures escalate, so do the total amount of radiation at all the available frequencies. This happens within a very short time span. Lastly, the absorption amount that a similar type of wave experiences is directly related to the pace of radiation of a specific type of electromagnetic wave. In this case, when a material radiates more red light thermally it means that its surface highly absorbs more red light. It is essential to note that in thermal radiation, only the travelling waves that are considered. (Kirk, 2006)Analysis of the radiating gases produced in combustionAn analysis of combustion process shows that various radiating gases are usually released in the process. This highly depends on the substance or material that is being burnt. Combustion can be analysed in different ways. This is considering the fact that there is complete combustion, incomplete combustion, smouldering and rapid etc. When a hydrocarbon completely burns in oxygen, it releases water and carbon dioxide. (Rasbash, 2004)Common oxides are however released when iron, sulphur, nitrogen and carbon are completely burnt. In this case sulfur releases sulfur dioxide and nitrogen releases nitrogen dioxide etc. In situations where there is incomplete combustion, hydrocarbons emit carbon monoxide, carbon dioxide when burnt. It is common for large radiation gas quantities to be released in during rapid combustion. Role of radiation in fire spread between neighbouring buildings and discussion on requirements for space separationRadiation plays a great role in fire spread between neighbouring buildings. This is considering the fact that through radiation, heat is highly transferred into the air. This heat can easily cause burning of combustible materials. In this case, a burning building releases heat into the air which in turn affects walls of neighbouring buildings leading to fire spread. This works by the substances of materials adjacent to the fire absorbing heat, starts smouldering and finally burns. (Kirk, 2006)Fire can easily spread from one building to the next through radiation if there is minimal spacing between the two. It is highly recommended that during construction, fire safety staff need to check on adjacent building and give relevant advice. Further research however shows that a space of ten feet should always be allowed between buildings to avoid fire spread by radiation. In this case, this should be five feet from the property line of the two structures. (Diamantes, 2003)
