Ra may produce alpha and alpha is He^2+. After giving electron to He^2+ it’s become to He that, it’s a noble gas.

The noble gas is Radon symbol Rn with atomic number 86 production as Radium with Z=88 emits a particle alpha so the atomic number of radiumis decreased by 2 units and the mass of radium by 4 units

Radium isotopes have two main forms of decay, alpha and beta minus. Alpha decay always produces a He-4 nucleus (that's what an alpha particle is) and helium is a Noble gas!. The beta minus will produce element #89 (not a Noble gas).

Radon is produced by uranium and radium decay, and
Helium is continually produced during the radioactive decay of radium
Radon
Discovered in 1900 by Friedrich Dorn, radon is a radioactive noble gas now regarded as a potential health hazard in some homes. It also has medical applications for cancer treatment. Its original name was to be niton for "shining" but it was eventually named as a derivative of radium. Radon is found in underground deposits where is it produced by uranium and radium decay.

Helium, the lightest of the inert gases, is continually produced during the radioactive decay of radium
