Note: I correct the given mistake only once. If you do not use the metric system, I will only make a single comment about it, even if it appears again in the rest of the article. If the draft has many language problems, I will only correct the most glaring ones. Unnecessary information will show as the copied text with the redundant information stricken through.
The containment room of SCP-XXXX should be surrounded by a continuous and unbroken four layered Faraday shield,
What is this, exactly?
in addition any extraneous electrical devices or EM wave emitting devices should be left outside the containment area unless required for testing purposes.
This is vague. Electromagnetic radiation includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.
Double door passages to the containment room should be mechanically locked and must be manned by at least two armed guards at all times.
No. Why would guards be necessary if the thing is already contained? This is a huge waste of man-hours. Many users interpret use of an excessively extreme containment procedures as an attempt to make an object seem more powerful or dangerous than it really is, and therefore assume that the author doing so is the sort of person who thinks that "dangerous" is the same thing as "interesting". Not saying any of this applies to you literally, but that will be a common perception.
Dimensions of the containment room should be approximately 30 m by 30 m by 40 m in size, allowing space to both fit SCP-XXXX and to allow adequate space for research and experimentation.
Why is the ceiling so high? That's a 7 story building we're talking about.
Reaching SCP-XXXX-1 has proven difficult, any organism with a nervous system that comes into close contact with SCP-XXXX-1 is killed within secondsdeath being associated with the nervous system and surrounding tissue being reduced to a gel of its original biological components. The cause of this being not entirely known, but having been associated with complex forms of electromagnetic and gamma radiation localized two meters around SCP-XXXX-1, but not otherwise escaping said radius.
I'm only going to mention this once, but the language in general is iffy. Here's what I mean:
Reaching SCP-XXXX-1 has proven difficult, [as] any organism with a nervous system that comes into close contact with SCP-XXXX-1 [How close is close?] is killed [expires] within seconds[comma] death being associated with [due to] the nervous system and surrounding tissue being reduced [reducing] to a gel of its original biological components. The cause of this being not entirely known [is not completely explained], but having [has] been associated with complex forms [complex forms?? They're wavelenghts] of electromagnetic and gamma radiation [Gamma radiation IS EM radiation] localized two meters around SCP-XXXX-1, but not otherwise escaping said radius [unnecessary].
Within a radius of at least 300m and retracting depending on the power supplied to SCP-XXXX, the EM wave SCP-XXXX-2 will be emitted from SCP-XXXX. SCP-XXXX-2 has a frequency range and pattern similar to human brain waves but differentiating in overall intensity and evolutionary pattern of the waveform.
Neural oscillation, as far as I'm aware, aren't the same thing as electromagnetic radiation. They're more of a way to describe neural behavior to put it in a perspective.
