Objective	Deliver 32x Crate of Contained Cerrocentite {320 m3)

Mission briefing
Okay, take a look at this. You know what this is? Yes, yes, it's a rock. It's a rare mineral, actually, called Cerrocentite. It has industrial applications, but it's mostly used in security systems. The reason it's in a special containment field is that it's also fairly radioactive. Take this shipment over to the manufacturers at <Station>, and don't bloody open it!

Redundant Systems

Security systems on stations are all-in-one, monitoring room occupancy, ambient temperature and humidity, and the gas mix from environmental control. It can be set to go on alert for various stimuli, and contains several redundant systems to ensure that an interrupt on one line does not prevent a problem being reported. Small pieces of radioactive material which are sensitive to various stimuli are an integral part of such systems.
