What are alpha and beta particles?
Alpha particles pose no direct or external radiation threat; however, they can pose a serious health threat if ingested or inhaled., beta particles. Some beta particles are capable of penetrating the skin and causing damage such as skin burns. Beta-emitters are most hazardous when they are inhaled or swallowed.
What are the 4 radioactive elements?
The common 4 radioactive elements are Uranium, Radium, Polonium, Thorium etc.
What are alpha beta and gamma rays?
Gamma rays are neutral, while alpha particles have a positive charge and beta particles have a negative charge. Two protons and two neutrons are bound together to form an alpha particle. High-energy electrons are known as beta particles. Gamma rays are photons, which are electromagnetic energy waves.
What is radioactivity?
Radioactivity is a process by which certain naturally occurring or artificial nuclides undergo spontaneous decay releasing a new energy. This decay process is accompanied by the emission of one or more types of radiation, ionizing or non-ionizing, and/or particles. This decay, or loss of energy, results in an atom of one type, ...
What is the radioactive gas that decays into water?
These radium isotopes further decay into the radioactive gas called radon (Rn 232 ). Both radium and radon are soluble in formation water under reservoir conditions and can be transported to the surface along with oil, gas, and produced water.
Why is the government working on plans to gather the soil and leaves contaminated with radioactive material and store them at designated
The motivation is to ease people’s anxiety in living close to radioactive material without thinking about the amount of radiation.
What is the wavelength of ionizing radiation?
Ionizing radiation is electromagnetic (in the form of waves with a wavelength of 100 nm or less, i.e. a frequency of 3 × 10 − 15 Hz or more) or corpuscular radiation that has sufficient energy to ionize certain atoms of the matter in its path by stripping electrons from them. This process can be direct (as with alpha particles) ...
What elements are in oil and gas bearing formations?
Many oil and gas bearing formations contain shales that have higher than average concentrations of uranium and thorium. These elements occur in chemical forms that are not water-soluble under reservoir conditions (U 238 and Th 232 ). U 238 and Th 232 decay into different isotopes of radium (Ra 236 and Ra 228 ).

However, for the case of radium discharged in produced water, risk assessment studies show that consumption of fish caught near produced water outfalls will not pose an unacceptable human health risk, even in the worst cases.
Is beta irradiation hazard severe?
However, as the external irradiation brought by beta particles is mostly confined to the epidermis and outer skin tissue, such external irradiation hazard is not too severe. Exposures are not limited to the intake of large amounts at one time ( acute exposure ).
