A radian, by definition, is a unit which connects the radius of an arc, the length of the arc and the angle subtended by the arc. A full radian is 360 degrees, hence we know that the Earth performs two radians when performing a full rotation around an axis.
Sarin Gas. â JULI BERWALD. Sarin gas (O-Isopropyl methylphosphonofluoridate), also called GB, is one of the most dangerous and toxic chemicals known. It belongs to a class of chemical weapons known as nerve agents, all of which are organophosphates.arin Gas. â JULI BERWALD.

Sarin, a nerve gas, can be absorbed through intact skin and be lethal at low concentrations. Thus if one needs to assess the risk of Sarin exposure one must take skin absorption and other routes into account but one cannot ethically test Sarin on human subjects; thus ways of modeling the risk from skin exposure of the agent have been found.
