The average daily solar radiation intensity in the north is 3.69 kWh/m2 and the south is 5.9 kWh/m2. The amount of solar radiation depends on the amount of cloud and the atmosphere of each locality. From one region to another, there is significant variation in solar radiation. Radiation intensity in the South is often higher than in the North. [47]
Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere. [1]: 26‑1 As a form of electromagnetic radiation, like light waves, radio waves are affected by the phenomena of reflection, refraction, diffraction, absorption, polarization, and scattering. [2]
The Ministry of Science and Technology (MOST, Vietnamese: Bộ Khoa học và Công nghệ) is a government ministry in Vietnam responsible for state administration of science and technology activities; development of science and technology potentials; intellectual property; standards, metrology and quality control; atomic energy, radiation and nuclear safety.
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volts (eV), which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms.
Function. Vietnam Atomic Energy Institute is a special ranked scientific organization under Ministry of Science and Technology, of which function is to assist Minister to perform duties including basic research, application and deployment of research results in the field of atomic energy, technical support for governmental management on atomic energy, radiation and nuclear safety, education ...
Radiative transfer (also called radiation transport) is the physical phenomenon of energy transfer in the form of electromagnetic radiation. The propagation of radiation through a medium is affected by absorption, emission, and scattering processes. The equation of radiative transfer describes these interactions mathematically.
In this time, Vietnam was under a central planned economy, with multiple U.S. sanctions and in a state of general poverty. To quote from the Dân Trí magazine: "During the late 70s and early 80s, [...], the nuclear physics discipline was forgotten without investment [from the government], and there were no state-level projects or projects for ...
Project SUNSHINE was a series of research studies that began in 1953 to ascertain the impact of radioactive fallout on the world's population. [1] The project was initially kept secret, and only became known publicly in 1956. [1]
