What is the balanced equation for rubidium-87 turns into strontium-87?
this is an example of β radiation, n -> p + e Rb-87 -> Sr-87 + e (rem to write atomic numbers in, Rb is 37 and Sr is 38) The halflife 87Rb is 4,88.1010 years.
Is iodine in nuclear bombs?
No. However one of the fission products produced is Iodine-131 and it appears in the fallout. Iodine-131 is a dangerous beta and gamma emitter with a halflife of 8.05 days, it concentrates in the thyroid gland and can selectively kill it or cause cancers in it. Fortunately the halflife is only just over a week, because it then practically disappears in about 5 to 6 weeks. This allows Iodine-131 contaminated food and drink (e.g. fresh milk) to be stored and then safely used when the Iodine-131 has decayed. This also makes it possible to protect the thyroid gland by saturating it with ordinary Iodine (usually as potassium iodide pills) until the Iodine-131 has decayed.
Do nuclear power plants produce radioactive substances?
Yes, but they also consume them. The uranium fuel used has a halflife measured in billions of years, the materials they produce have halflives measured in only hundreds or thousands of years. So in the long term balance of things they consume radioactive substances faster than they produce them.
What element is used to make nuclear weapons?
Uranium-235Uranium-233Plutonium-239DeuteriumTritiumAs tritium is radioactive with a short halflife (12 years), weapons using it age rapidly possibly becoming unreliable. Therefore it is normally produced from Lithium (in the form of Lithium Deuteride) by fission neutron bombardment just before fusion is initiated.
What is the atomic mass of uranium239?
Uranium is a radio active metal element. Atomic mass of it is 239.
When was Illadelph Halflife created?

What is the correct order of nuclear decay mode for the changes from U-238 to U-234?
U-238 --> alpha + gamma + Th-234, halflife 4.51E9 yearsTh-234 --> beta- + gamma + Pa-234, halflife 24.10 daysPa-234 --> beta- + gamma + U-234, halflife 6.66 hours
Is lambda the halflife logo?
The logo has a border, however the lambda is in the center.
