Isotopes Intro
Nuclear reaction
Nuclear reactions is the bombardment of an atomic nucleus with an energetic particle causes a change in the identity or features of the nucleus. An alpha particle, a gamma-ray photon, a neutron, a proton, or a heavy ion could be used to bombard the target. In any scenario, the bombarding particle must have enough energy to get close enough to the positively charged nucleus to be inside the strong nuclear forces’ range.

Radioactive decay
The act of producing radiation spontaneously is known as radioactivity. Radioactivity is a physical phenomenon, not a biological one. Simply put, the radioactivity of a sample can be determined by counting the number of atoms that decay spontaneously each second. This can be accomplished using devices that identify the specific type of radiation emitted at each "decay" or disintegration. The emission of energy in the form of ionising radiation is known as radioactive decay. Alpha particles, beta particles, and/or gamma rays are examples of ionising radiation that can be emitted. Radioactive decay happens in radionuclides, which are imbalanced atoms.
Half-Life
In radioactivity, the half-life is the time it takes for one-half of a radioactive sample’s atomic nuclei to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time it takes for a radioactive material’s number of disintegrations per second to decrease by one-half.
31P vs 32P
31P
31P
STABLE no half-life (only stable Phosphorus isotope)
Boiling point: 280.5 C
Atomic mass: 30.973762
15 protons 16 neutrons
Uses
31P is particularly useful in probing cellular energetics as it can detect the basic energy unit within the cell, adenosine triphosphate (ATP)
32P
32P
Half-life: 14.3 days
Boiling point: 280.5 C
Atomic mass: 31.97390
15 protons 17 neutrons
What is 32P used for
Chromic phosphate or 32P is used to treat cancer or cancer related problems.
Purpose of 32P
When was 32P introduced
When was 32P introduced
32P phosphate was the first therapeutic radioisotope, used in leukaemia about 70 years ago.
What are therapeutic radioisotope
What are therapeutic radioisotope
Radioisotope therapy is a procedure in which a liquid form of radiation is administered internally through infusion or injection
What types of cancer does 32P treat
What types of cancer does 32P help treat
It helps with a blood disorder called polycythemia vera and certain types of leukemia
It is sometimes surgically inserted into the pleura (sac that contains the lungs) or into the peritoneum (sac that contains the liver, stomach, and intestines) to treat the leaking of fluid inside these areas that is caused by cancer.
It may also be given by injection to treat cancer in certain organs such as the ovaries and prostate.
Impact of 32P
Benefits
It literally helps cure cancer
Impact of
32P
Hazards
Phosphorus P 32 gives off radiation that damages the DNA in a cell, which can cause the cell to die. Irresponsible or non-profesional use can lead to serious injury and/or death
