Most chemical disasters involve chemicals which are highly reactive in the environment. As such, they are almost immediately reacted to form less harmful chemicals than their original forms. Upon contact with water, some chemicals may also dissolve into concentrations which are not deemed as harmful to the humans or environment.
Also, chemicals tend to be more dense than air. As such, upon exposure, they sink to the bottom rather than remain in the atmosphere. This reduces the radius in which the chemical can spread as containment measures come into place.
In contrast, radiation from nuclear plants cannot be easily dispersed by the environment as they have a very long half life. As such, they are able to spread over large distances.
Furthermore, while containment measures for chemical accidents are usually straight-forward (through neutralisation, chemical reaction, precipitation etc), the only way to contain radiation is to physically contain them in lead barrels; an impossible task once a nuclear plant has leaked. That is why nuclear plants have a containment vessel made up of lead which will melt upon an accident so as to contain the nuclear waste.
Radiation disasters typically affect a larger area than chemical disasters due to the nature of radiation. Radiation can travel through air, water, and even be carried by wind, affecting a wide geographical range. In contrast, chemical disasters are often more localized as chemicals tend to disperse less easily and are restricted by their physical properties.
Radiation disasters are made for spreading, so it more dangerous than chemical disasters
It's because radiation is 'made' to spread.
the bonds get larger and more bonds are created
Yes
A black surface absorbs the heat radiation and a white surface reflects the heat radiation
Gum and wood chemical producers are part of the larger industrial organic chemical industry.
Tornadoes could probably be considered the smallest of natural disasters, that is they affect the least amount of area but can still devastate communities. Tornadoes are also among the most difficult natural disasters of not the most difficult to measure. By comparison other types of storm are larger an longer lasting, which makes measurements easier while major earthquakes are generally limited to specific geographic regions, allowing instruments to be put in place ahead of time.
The importance of a chemical bond is to create molecules. So matter is larger.
Generally the larger the meteorite the larger the crater.
The larger the surface area, the larger the damping of an oscillation
Yes, they are longer. Longer wavelengths are lower energy.
Neutron therapy can treat larger tumors than conventional radiation therapy
