his theory was that the alpha particles would pass straight through the gold atoms with slight deflection due to the positive charge thought to be spread out in the gold atoms.
When they tested the theory, they were suprised that a great majority of the alpha particles passed staight through the gold atoms withought deflection. even more suprizing a small fraction of the alpha particles bounced off the gold foil at very large angles. some even bounced strait back toward the sourse. Rutherford later recollected"this is almost as increadible as if you fired a 15 inch shell at a peice of tissue paper and it came right back and hit you"
Dosimeter badges typically do not detect exposure to alpha particles because alpha particles cannot penetrate the outer layers of the badge to reach the dosimeter inside. Alpha particles are stopped by even a thin piece of clothing or the dead layer of skin, so they are not typically captured by external dosimeters worn by radiation workers. Specialized internal dosimeters may be used to monitor alpha particle exposure if it is a concern in a particular workplace setting.
William Lever provided his workers with decent wages, access to affordable housing, and various amenities such as libraries, recreational facilities, and healthcare. Lever believed in improving the overall well-being of his workers and their families through his progressive approach to employment.
Workers stationed at a moving track to attach parts are often referred to as assembly line workers or line workers. Their role involves inserting components into products as they move along the production line.
According to the theory of the iron law of wages, wages tend to fluctuate in cycles based on supply and demand. When there is a surplus of labor, wages tend to decrease, as employers have more options and can pay workers less. Conversely, when there is a shortage of labor, wages tend to increase as employers need to compete for workers.
The reason you feel the explosion in your feet before you hear it is due to the difference in the speed of sound through different mediums. The shockwave travels faster through solid material (like the ground) than through the air, so you sense the vibrations in the ground before you hear the sound through the air.
Rutherford was expecting the result to be what JJ Thomson had predicted. That the Alpha Particles just pass through the gold foil, not rebound, like the result. JJ Thomson thought of this result because of his plum pudding model.

The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.
You'd be surprised how little they cover. Most hospitals don't even recognize them.
Rutherford B. Hayes was the president during this time. His role was to try and resolve the issue while pleasing not only the railroad workers but also the rest of the country.
Gunite particles can be dangerous to health. For workers routinely exposed to the particles, OSHA says that silicosis can develop.
Workers' College's motto is 'Education through Civil Service'.
Only workers in mills that manufacture yarn, thread, or fabric have a significant risk of dying of this disease.
More than 800,000 workers in the cotton, flax, and rope-making industries are exposed in the workplace to airborne particles that can cause byssinosis.
The plum pudding model of the atom was not correct. The prediction that alpha particles would pass through a sample of matter and would be deflected only minimally was disproved by rutherford and co-workers who found that some alpha particles (1 in 8000) bounced almost straight back. This was explained by the presence of a nucleus. Other phenomena were also difficult to explain. For example atomic absorption spectra with the sharp, principal and diffuse lines.
