If it's based on an imploding fission primary, increasing the strong force will prevent fission. Unfortunately increasing the strong force will enable more fusion events for deuterium/tritium boosted devices or primary fusion triggered weapons. The latter should be feasible at typical Traveller tech levels. Additionally, weapons could have their own damper units to reduce the required critical mass for fission or pressure/temperature for fusion. Book 4 introduced the mini-damper units to stabilise californium based ammunition, after all. Overall the goal of the damper user is to produce a fizzle as Rupert Boleyn points out - if the nuclear portions explode sufficiently to wreck the warhead then you are left with a kinetic kill device. > 2.

Again, how would this > work? The contaminants of interest are relatively long-lived fission products. Induced radioactives created by neutron capture (neutron activation products) have very short half-lives - so after 30 hours they are 10% of the initial intensity. Nuclear dampers would be used to accelerate decay via enhancing the weak force. This could be a real problem for living things in the contaminated zone given the presence of potassium-40 in cells. 2g/kg of an animal's body weight is potassium. 0.012% is potassium-40. Causing all of this to beta-decay to calcium-40 releases ~750kJ of heat into each kilo of tissue. Sizzle and splat. The only saving grace is that K-40 has a half-life of 1.2 billion years. The typical zoo of fission products have shorter half-lives than that. Notable examples because of their abundance: caesium-137: 30 years strontium-90: 28.8 years From Glasstone and Dolan "Effects of Nuclear Weapons" 3d. ed p.19: "More than 300 different isotopes of 36 light elements, from zinc to terbium, have been identified among the fission products... The half-lives of the fission products have been found to range from a small fraction of a second to something like a million years." Note that all of a primary may not be consumed in the explosion, so: plutonium-238: 88 years Pu-239: 24,000 years Pu-240: 6,560 years So the hope is that decay rates can be finely controlled with damper technology. Dampers are very good sterilisers or anti-personnel weapons in malicious hands. Rob O'Connor
