The difference between the two rounds comes down to their ability to handle maximum pressure. SAAMI lists the maximum average pressure for .223 Remington ammo in a .223 chamber as 55,000 psi with bullets ranging from 35- to 77-grains traveling anywhere from 4,000 to 2,785 ft. per second velocity. Langsteger W. (18)F-NaF PET/CT: EANM procedure guidelines for bone imaging. Eur J Nucl Med Mol Imaging. 2015 Oct;42(11):1767-1777. doi: twist should shoot 55 grain lead okay, so would probably (I don’t know) shoot 40 grain non lead bullets, especially those BT ones if you remove the tips. One of the most often seen tropes in the gun community– and even by some in the firearms industry to an extent– is that the designations “223 Remington” and “5.56x45mm NATO” are used interchangeably in a sort of “six of one, half a dozen of the other” kind of indifference.

Vali R, Alessio A, Balza R, Borgwardt L, Bar-Sever Z, Czachowski M, Jehanno N, Kurch L, Pandit-Taskar N, Parisi M, Piccardo A, Seghers V, rounds are most effective when fired from a distance of 100 yards or less. Beyond that distance, the round begins to lose its accuracy and effectiveness. Ronen, Yigal; Shwageraus, E. (2000). "Ultra-thin 241mAm fuel elements in nuclear reactors". Nuclear Instruments and Methods in Physics Research A. 455 (2): 442–451. Bibcode: 2000NIMPA.455..442R. doi: 10.1016/s0168-9002(00)00506-4. There are a lot of factors that go into determining which is better, 308 or 223. It really depends on what you’re looking for and what you’re trying to accomplish. If you’re just starting out, then the 223 is probably the better choice. It’s less expensive and has a shorter learning curve. However, if you’re looking for more power and accuracy, then the 308 is the way to go. Aug;37(8):2497-2508. doi: 10.1007/s00381-021-05199-4. Epub 2021 May 10.

As discussed in more detail in other sections, in the interest of safety it is advised by firearms industry experts that “5.56” marked ammo may be unsafe to fire in a rifle or pistol listed as being chambered for .223 Remington. Oct;42(11):1750-1766. doi: 10.1007/s00259-015-3135-1. Epub 2015 Jul 25. PMID: 26205952. Radiopharmaceutical Therapy Shulkin BL, Zucchetta P, Lim R.

J Nucl Med. 2021 So, to reiterate, while the exterior physical dimensions of both commercial .223 Rem and 5.56 NATO are identical, 5.56 ammo can often be loaded to higher pressures than .223 and, as such, firearms with a 5.56 chambering are larger in key areas to accept that greater potential pressure.
Americium-241 decays by alpha emission, with a by-product of gamma rays. Its presence in plutonium is determined by the original concentration of plutonium-241 and the sample age. Because of the low penetration of alpha radiation, Americium-241 only poses a health risk when ingested or inhaled. Older samples of plutonium containing plutonium-241 contain a buildup of 241Am. A chemical removal of americium from reworked plutonium (e.g. during reworking of plutonium pits) may be required. a b #– Values marked # are not purely derived from experimental data, but at least partly from trends of neighboring nuclides (TNN).
