Picture of Scp-XXXX when found by containment agents.
Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures:All personnel that enter CU-████ must wear the radiation and hearing protection provided in the airlock. Failure to do so will result in radiation poisoning and hearing loss with extended exposure. See addendum SCP-XXXX-Safety Sheet 001.
SCP-XXXX is to be kept in a lead lined, foam fitted, storage case in containment unit CU-████ at Site-████. SCP-XXXX-1 is to be kept in a lead lined, foam fitted, storage case at least 2.1 meters away from SCP-XXXX.
Access to SCP-XXXX is restricted to personnel with level 3 access or above. Experiments involving SCP-XXXX must be approved by the Containment Leader and by Site-████'s chief radiobiologist. All experiments must be attended by at least one medical staff and one radiobiologist with level 3 clearance or above.
After all experiments performed with or on SCP-XXXX, the object locker, the experiment area, and all exposed clothing, equipment, and or personnel must go through level 4 decontamination procedures outlined in document SCP-XXXX-Decon01
Description: SCP-XXXX is a ((Insert description of a 4/4 cello made in the 1940s. Please include measurements in Metric. The wood, catgut, and metal strings are normal except for the presence of exotic matter that has yet to be determined. )) SCP-XXXX-1 ((Insert description of the bow. Please include measurements in metric. The wood and horsehair are normal except for the presence of exotic matter that has yet to be determined.)).
When SCP-XXXX-1, further referred to as bow, is drawn across the strings of SCP-XXXX electromagnetic (EM) wave lengths are produced. The EM wave lengths range from 23 nanometers to 126 mircometers, depending on which and how each string is hit by the bow. The strings also produce equivalent ultra-high frequency sound waves at the same hertz as the EM waves; causing deafness in any operator with prolonged exposure. Hearing protection is required during experiments. See Incident SCP-XXXX-INC:001.
