Target class: actinide isotope Context triple: [fermium-252, instanceOf, actinide isotope]
-
A.
chemical isotope
chosen
A chemical isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons in its nucleus, resulting in a different atomic mass.
-
B.
helium isotope
A helium isotope is a variant of the helium atom that has the same number of protons (two) but a different number of neutrons, resulting in distinct atomic masses and nuclear properties.
-
C.
plutonium production reactor
A plutonium production reactor is a nuclear reactor specifically designed and operated to irradiate uranium fuel and efficiently generate plutonium-239 for use in nuclear weapons or reactor fuel.
-
D.
isotope production facility
An isotope production facility is a specialized installation that generates radioactive or stable isotopes—typically using reactors, cyclotrons, or accelerators—for use in medicine, industry, research, and energy applications.
-
E.
radioactive material
Radioactive material is any substance that contains unstable atomic nuclei which spontaneously emit ionizing radiation as they decay into more stable forms.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
