14. It's Wrong And It Doesn't Matter
As others have said, the bomb was a fission bomb based upon U-235. The Nagasaki bomb was plutonium based, implosive compression in design. There were no H-bombs until about 6 years after WWII.

However, even if it's an H-bomb, the radiation levels are still quite high. The primary reason (excluding the fact that the enormous energy release still liberates high levels of gamma and high X-ray) is that in order to initiate the fusion, an thermonuclear device still requires a smaller fision device. So, there is a chemical explosion that initiates the fission, which then detonates with a very high energy output to trigger the fusion. The net output of radioactivity is correlated to the total energy release and radioactive decay materials are related the total energy release of the fission device.
