Yes, but the rate of decay depends on the conditions.
Yes.
alpha decay
No such thing as ratio decay. Sorry
There are 3 naturally occurring isotopes of Uranium, all decay by alpha to Thorium:238U --> 234Th + 4He235U --> 231Th + 4He234U --> 230Th + 4He
After decay Carbon 13 then will become classified as stable.
Yes.

The rate of decay for a lollipop wrapper depends on the construction of a wrapper. If it is paper, it will decay in a few months. Plastic may take centuries. Foil will take about 25 years.
Objects that are rich in carbon rot, decay, and break down to form compost. Examples are brown compostable materials, such as fallen leaves. Other objects that are rich in nitrogen likewise rot, decay, and break down. Examples are green compostable materials, such as freshly cut grass clippings. And still other objects such as paper and paper products, similarly rot, decay, and break down.
gamma decay beta decay alpha decay
I believe relative decay is the decay over time.
The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.The decay of radioactive isotopes.
The natural isotope 227Ac decay: - by beta minus decay: to 227Th - by alpha decay: to 223Fr
Radium-226 does not decay by beta decay. It decays by alpha decay to radon-222.
The 3 things that can happen during radioactive decay is the 3 parts of decay: Alpha decay, Beta decay, and Gamma decay. In alpha decay, which is the weakest part of decay, it has a positive helium neuclus(2 protons and 2 neutrons), and the particles will burn your skin, but can be easily stopped by a peice of paper. This is the most ionising as the helium nucleus can take electrons from other atoms and make them unstable. This can give rise to cancers as it distorts cells. In Beta decay (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus" (β−). It can be stopped by 3mm of aluminum. Gamma decay, which is the strongest, can only be stopped by 3cm of lead. It has electromagnetic waves, it contains the most energy, and therefore is the most penetrating, but normally it just passes straight through the human body. Radioactive decay can be very harmful, and its best to stay away. This question has been anwsered by Rae-Ann Salisbury.
