SCP-2655-G

The fifth and current instance of SCP-2655-G, former researcher Aela.

## **`DESCRIPTION`**

SCP-2655-G is an affliction related to an event by which a species becomes the carrier for an unknown means of producing a gradually increasing, deadly form of ionizing radiation. The phenomena first came to the Foundation's attention when reports of a glowing frog owned by a nine-year-old boy named Jack Andrews in Bakersfield, California reached Foundation ears.

At the time of recovery on July 7, 2013, the frog was producing a constant 0.03 Curies (ci) worth of ionizing radiation. This rate had been steadily increasing by by 5.1% every six days since initial discovery.

It was also noted that the frog had the number '3' visible on its back. Although the marking wasn't any known form of ink or other coloring substance, but rather an altered pigmentation of its skin.

Based on projections by Foundation researchers, the frog would have had a radiation output of no higher than 0.001 ci when it was first discovered by the child in July of 2012.

On September 23, 2013, the frog was found dead. At the approximate time of death, the frog's radiation output had reached approximately 0.059 ci. The SCP was reclassified as neutralized.

At 8:17 pm, approximately 3 hours after SCP-2655-G was classified as neutralized, its radiation output briefly increased from 0.059 ci to 10 ci, a jump of over 169 times its previous output.

Within 10 minutes, the frog vanished from containment and reappeared in the possession of Jack Andrews, who was located in the Site-22 cafeteria while being held for continued questioning, before his planned amnesticization and release.

After approximately 1 minute, Jack begins having a seizure. He releases a burst measuring at 43 ci of gamma radiation, resulting in 6 deaths and an additional 9 to be treated for severe radiation poisoning. Among the deaths are those of his parents, who were also being detained for questioning.

Jack was taken to a lead lined containment chamber and given the formerly discontinued classification of SCP-2655-G. Upon study of the child, the number '4' was found on his back, mirroring the numbering of the previous SCP-2655-G instance.

It was discovered that Jack's rqadiation output was significantly higher, beginning at 2 ci and increasing by 7.3% every 6 days.

After a researcher mistakenly mentioned to Jack the death of his parents, Jack Andrews had begun to express depressive and self destructive tendencies, and was placed under constant surveilence.

On September 30, 2014, over 1 year since his containment, Jack Andrews was found deceased in his cell, of an apparent self termination. By his death, Jack Andrews had been producing a steady 157.8 ci worth of radiation.

Within several hours, researcher Aela, who had been in charge of feeding both instances of SCP-2655-G, began to exhibit symptoms similar to that of Jack Andrews. She was moved into containment and, after careful consideration, designated as the new instance of SCP-2655-G. Similar to the previous two instances, former researcher Aela has the number '5' located on her back.

Upon initial containment, former researcher Aela was producing 7 ci worth of radiation, which began to increase by 9% every five days.

**`ADDENDUM:`** Over the course of containment, foundation researchers have attempted to discern a pattern as to the radiation output of each subsequent iteration, so as to better aid in future containment. So far, researchers have theorized the following:

* Upon death, the SCP-2655-G instance will jump approximately 169.5 times its previous radiation output.
* Once the deceased lifeform transports to a new host, the radiation will increase by an additional 4.3 times.
* After this, a number will appear on the new host's back that is exactly one digit higher than the former host, as detailed in our modern Hindu–Arabic numeral system.
* Each increase of the base starting ci of each instance is reduced by approximately 1/571 of its former increase.
* The percentage increase in radioactivity per time period increases starting at 1.8 x and decreasong by 0.2 x per each new instance.
* The amount of time required for each jump in ci levels is reduced by 1.2 times per approximately every 2 instances.
* This means that:
	+ **{Bold denotes hypothetical information}**:
		- **Instance 1 began at 0.0000000000000294 ci**
			* **1.77% ci increase every 7 days**
			* **UNKNOWN MAXIMUM REACHED**
			* **MINIMUM OUTPUT AT DEATH: 0.0000000000049833 ci**
		- **Instance 2 began at 0.000000000711 ci**
			* **3.18% ci increase (1.8 x instance 1) every 7 days**
			* **UNKNOWN MAXIMUM REACHED**
			* **MINIMUM OUTPUT AT DEATH: 0.0000001205145 ci**
			* **MINIMUM OUTPUT UPON BECOMING NEW INSTANCE: 0.0000000155463705 ci**
		- **Instance 3 began at 0.001 ci**
			* 5.1% ci increase (1.6 x instance 2) every 6 days
			* MAXIMUM: 0.059 ci
			* OUTPUT AT DEATH: 10 ci
			* **MINIMUM OUTPUT UPON BECOMING NEW INSTANCE: 0.00002042720775 ci**
		- Instance 4 (Jack) began at 2 ci
			* 7.3% ci increase (1.4 x instance 3) every 6 days
			* OUTPUT AT DEATH: 157.8 ci
			* OUTPUT UPON BECOMING A NEW INSTANCE: 43 ci
		- Instance 5 (Aela) began at 7 ci
			* 9% ci increase (1.2 x instance 4) every 5 days
			* **OUTPUT AT DEATH: PENDING**
			* OUTPUT UPON BECOMING A NEW INSTANCE: 678.54 ci
		- **Instance 6 WILL begin at 7.006 ci**
			* **9% ci increase (1 x instance 5) every 5 days**
			* **OUTPUT AT DEATH: PENDING**
			* **MINIMUM OUTPUT UPON BECOMING A NEW INSTANCE: 30.1 ci**

It is theorized that the increase of radiation per instance over time will level out by instance 10, at 0.35% ci increase per every 3 days. It is also likely that the increase of ci output from instance to instance will level off after or around instance 6. Therefore, the request to increase the threat level to Keter has been denied.

## **`CONTAINMENT`**

Site-22.

Based on current calculations, it would take over 97 thousand years if each instance starting from 10 lived 3 days, before radiation levels grew to pose a risk of significant nuclear fallout, in line with the radiation levels posed by the Nagasaki and Hiroshima bombs. However, to further mitigate this risk, all new instances are to be exposed only to D-Class personnel provided with protective suits to best ensure that only expendable, on-site personnel are chosen as the next instance. And all new instances starting with instance number 6 are to be terminated after approximately 2 days.
