Answer:
Both thermonuclear weapons and atomic bombs are capable of releasing significant amounts of ionizing radiation, which can cause damage to living cells and increase the risk of cancer and other diseases. However, in terms of radioactivity, there is no clear answer to which weapon is more radioactive, as it depends on a variety of factors, including the design and yield of the weapon, the materials used, and the conditions under which the weapon was detonated.
In general, both thermonuclear weapons and atomic bombs can produce a wide range of radioactive isotopes, including fission products, activation products, and residual materials from the bomb casing and other components. The radioactivity of these isotopes can persist for varying amounts of time, ranging from seconds to thousands of years.
Therefore, it is difficult to compare the radioactivity of thermonuclear weapons and atomic bombs in a simple way, as the answer depends on many factors. However, it is clear that both types of weapons can produce significant amounts of ionizing radiation, which can have serious health effects for those exposed to it.
