Natural Uranium contains about 99.2745% of U-238 isotope.
Its half-life is 4.468E+9 years.

Some significant facts about U-238 decay:
Decay mode: alpha (100%), Q-value=4270 keV
Gamma rays: 49.55 keV (0.064%), 113.5 keV (0.0102%)
X-rays: 16.202 keV (3.0%), 12.968 keV (2.5%), 18.980 keV (0.69%), ...
Alpha rays: 4198 keV (79.0%), 4151 keV (20.9%), 4038 keV (0.078%)
Spontaneous Fission: 5.45E-5%
Decay heat: 8.508E-9 W/g
