Object Class: Euclid
Special Containment Procedures:
Item SCP-019 is to be kept in a securely locked containment cell, covered with at least 5 feet of lead and 30 feet of concrete. The cell is to be separated by a double air-lock with reinforced shielded bulkheads and is to be equipped with its own atmosphere and temperature regulation system. The area is to be kept below -10 degrees Celsius (14 Fahrenheit) at all times. In the event of power failure, a backup generator will activate. Should the backup generator fail, liquid nitrogen will be fed in SCP-019's cell at a constant rate with enough to last for 10 hours.
No fewer than 5 personnel may enter SCP-019's cell at any given time. All entering SCP-019's cell must wear armored class IV anti-radiation/anti-electrical suits (HAZMAT-cIV). At least three additional personnel are required to company all entering SCP-019's cell and are to be equipped with liquid nitrogen spray guns to subdue SCP-019 if necessary.
Found in the wreck of a Russian nuclear submarine in the Arctic Ocean on February 1985. SCP-019 is the size of an average adult human male and is composed of a glowing pale green translucent material with its skeletal system fully visible. SCP-019 emits high power gamma radiation at all times and has a strong electric current capable of subduing unarmored personnel by touch. SCP-019 has an average body temperature of 30 degrees Celsius (86 degrees Fahrenheit). As the body temperature of SCP-019 rises, its radiation and electrical output increase exponentially (increasing by a factor of e for every 10 degrees).
SCP-019 has roughly five times the strength of a physically fit human male, is extremely hostile and will attack at the first chance possible. SCP-019 possesses rudimentary intelligence and has been conditioned to not attack through high pressure blasts of liquid nitrogen. SCP-019 is to be fed a daily diet of protein-rich food(preferrably meat). SCP-019's containment cell is to be cleared of radioactive dust and excrement weekly.
Additional: As of January, 2008, subjects radiation output remains the same as when first discovered.
