On first glance appearing similar to a dull iron but with a slight deep red glow at room temprature and will always be slightly warmer than the surrounding enviroment due to the radiation emmitted from the elementss mild instabilty

The super heavy properties of SHSE's make the metal very soft comparable to gold on its own. The metal has by far and away the single best gamma blocking ability of any element in existance because of the density, being nearly three times as effective per metre as lead. The metal is not very reactive but will oxidise quickly requiring a shielding component or an alloy to remain uncorroded espessially in atmosphere. The metal has no magnetism of any kind, but does conduct electricity even better than gold which can be a double edged sword when working with the material as any loose wire that comes into contact with a SHSE plating is an imediate danger. The final property of note is the low temprature heat given off by the material naturally decaying into more stable elements, while its own decay releases alpha radiation along with the next three decays, as it gets further and further down towards Fermium, where a period of stability again sets in, gamma radiation will be emitted in these steps so a smaller lead radiation shield is advised.

SHSE has a half life of 50,000 years which while to begin with is not fissile after 2000 years of background radiation in low earth orbit or 10 years in orbit around Europa, due to the high background radiation, would have enough decayed particals polluting it to become fissile and would cause a low level sustained fission reaction increasing temprature which has lead to multiple accidents when proper maintance is not done on ships travelling through highly radioactive sections of solar systems.

The almost sole use for material compounds made from SHSE is as radiation shielding for cargo ships, especially those which need to brave very highly radioactive orbits such as Jupiters. SHSE can be found on almost any deep space worthy ship even in those commuting to less hostile planets to keep the crew secured from hostile cosmic rays. The material becomes less and less needed however as technology improves and makes more safe options such as mobile Synthetic Magnetosphere Generators. SHSE's sudden fissile potential if the entire shielding isn't replaced leads to constant accidents especially around Jupiters moons where crews are suddely cooked alive by their ships hull turning into a nuclear reactor and overwhelming the ships heat dumps.
