Not necessary for natural uranium; the most energetic gamma radiation of natural uranium has an energy of only ca. 183 keV uranium; uranium is not so dangerous as a radioactive element. Uranium is more toxic - ingested or inhaled.
None. A pellet of uranium contains uranium, not coal.

In terms of potential energy, one pellet of uranium contains much more energy than coal. It is estimated that the potential energy in one pellet of uranium is equivalent to burning several tons of coal. This is due to the high energy density of nuclear fuel compared to fossil fuels.
Any pellet gun should be handled like a real firearm. Yes you can be killed with a pellet gun under the right circumstances.
A 7 gram uranium pellet can generate a significant amount of power through nuclear fission. The exact amount of power produced would depend on the specific isotopes of uranium present, as well as the efficiency of the nuclear reactor or device in which it is used.
Depends on the size of your pellet. 1 kg of Uranium235 is equivalent to 1500 tonnes of coal.
7 g 235U is approx. equivalent to 20 t coal (for the complete fission of the uranium).
Approximately 30,000 kilograms of coal would need to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet. Uranium fuel has a much higher energy density than coal, making it a more efficient and cleaner source of energy.
You are orobably thinking of the small cylinders which make up the fuel rods. These are 10mm diameter and about 10mm long, and are packed end to end inside the zircaloy sheath to make a fuel rod. The material is uranium dioxide with the uranium enriched to about 5% U-235.
There are many types of uranium pellets depending on the nuclear reactor type and the used uranium enrichment (or uranium-235 content). It may be more illustrative to say that: 1 gram of uranium-235 when undergoes fission in a nuclear reactor gives energy roughly equivalent to burning 3 tonnes of coal or 2 tonnes of oil.
# I'm not clear what size pellet you mean. However for Uranium235 (the fissile isotope), if it is fully used up, 1 kg will give as much energy as 1500 tonnes of coal, ie 1,500,000 kg of coal, so that is the ratio, 1,500,000 to 1. Of course uranium as loaded into the reactor is actually about 4 percent U235, the rest U238 which is not fissile, so the U235 is 1/25 of the total weight of uranium, and if you mean the total uranium weight you therefore have to reduce this ratio by 25, and get 60,000 to 1.
A stick of uranium is typically referred to as a fuel rod in the nuclear industry. These fuel rods are used in nuclear reactors to sustain a controlled fission chain reaction, producing heat that is converted into energy.
