Although the applications of radioactive substances have brought great progress for human society, but it also brought the radiation pollution problems, which had rang the alarm bells for human beings. Dirty bomb is a kind of bomb with huge destructive power, although it have not been heard that  which country has used dirty bombs. But since dirty bombs are easy to make, and it's easy to be used as a tool for making the terrorist attacks by the terrorists. So we still have to pay great attention to the prevention of dirty bombs and to take certain measures to shield their super radiations.

 

First of all, we should be in the form of law to explicitly prohibit the uses of dirty bombs, any countries, any persons can’t use any reasons to use the dirty bombs. Secondly, the states must strengthen the supervision of the use of radioactive substances. In addition, we can use the tungsten alloy shielding containers to store the radioactive dirty bombs, which have been manufactured, or already exists. The reason for using tungsten alloy shielding containers to shield the dirty bombs is that the tungsten alloy has great highly density and good corrosion resistance, which can not only have the good radiation shielding capacity for the dirty bombs, but also have the long storage capacity, in order to avoid the problems of the dirty bombs leaking that caused by corrosion of the containers. Finally, if one area is attacked by the dirty bombs, the government should immediately command people to evacuate from the area, in order to ensure the safety first of all, then enclosing the area and taking the scientific management to treat the radiation problems.
