For the most part I enjoyed this but as pointed out it is a bit too similar to 3001.
Aside from that though my biggest bugbear with this story is the the part where he mentions the door being on the other side of the room just beyond the scp. This would be fine if the door was unlocked but it's mentioned in the article that it's a sealed bulkhead. Again this would also be fine as the researcher may not know this but even if they don't know that to be the case why don't they just close their eyes?
Also the "we die in the dark so you can live in the light" line fits this scp perfectly. Even if it is a bit on the nose I feel like it should have been in there somewhere. Maybe at the end a bit saying the researcher was posthumously awarded something or other, then that quote. If I was doing that though, I'd probably want to make the death a tad more meaningful. That could be done quite easily though.
If it was me if probably increase the length of time from seeing the object to head exploding. I'd make it so that it was apparent from d class testing that there was something more to the explosions. Perhaps the victim becoming aware of some unbelievable truth before hand but due to threats against d class being useless when your blowing them up anyway the foundation haven't been able to figure out what they know. The heroic action performed by the researcher was simply explaining the process of death via this object. Whether or not the reader finds out what this truth is, is secondary in my view.
That justifies the posthumous award, the fitting (if slightly obvious) quote and also addresses the above users criticism of the log being kind of redundant.
The only problem, after typing all that out, is that making it a story about a foundation employee describing death via an scp object unfortunately makes it even more like 3001. I understand the problem writing a story like this a little bit more now and as a result have to say I've enjoyed this story more than I initially thought.
