Final answer:
The statement is true; thermonuclear bombs are more destructive and costlier to produce than other types of bombs due to the complex technology needed to combine fission and fusion reactions, resulting in very high energy yields.
Step-by-step explanation:
True, a thermonuclear bomb does more damage than other kinds of bombs and is very expensive to make. Thermonuclear bombs use a combination of nuclear fission and nuclear fusion to produce a massive explosion. The construction of a thermonuclear bomb involves using a fission bomb to ignite the fusion fuel, like lithium deuteride. The resulting explosion can generate energy yields measured in kilotons (kT) or megatons (MT) and can be significantly more powerful than fission bombs alone or conventional explosives. Thermonuclear bombs are known for their devastating thermal and nuclear radiation outputs and can have explosive power up to a thousand times greater than the bomb dropped on Hiroshima. They can vary in yield from about 0.1 kT to over 20 MT, with historical tests revealing detonations up to 67 MT as was the case with a test conducted by the USSR.
It is important to note that the expense in creating a thermonuclear weapon pertains not only to the cost of the materials but also to the complex technology and infrastructure required for their development and testing. Additionally, there are ethical, legal, and geopolitical implications surrounding the manufacture and possession of such weapons. As a result, these weapons are typically produced by countries with advanced nuclear technology and significant economic resources.
