Radiation travels from its source in the form of energy waves or energized particles. There are actually two kinds of radiation, and one is more energetic than the other. It has so much energy it can knock …
MARE will provide valuable data on radiation levels during missions to the Moon, and assess a new radiation-shielding vest for crew. Data from all three "passengers" will help NASA protect astronauts …
The risk of harm from radiation depends on the amount of dose, the dose delivery rate, the type of radiation, the sensitivity of the tissue exposed, and the gender, age and health of the exposed person.
Niels Bohr in 1913 combined Rutherford’s concept of the nuclear atom with Planck’s idea of the quantized nature of the radiation process and developed an atomic model that successfully deals …
Our sealed Cs-137 source emits radiation at a rate of 5 μCi (1.85 x 105 disintegrations/sec). Don’t stop work altogether! You can minimize the risk using three basic practices: Reduce the amount of time …
This report describes sources of ionizing radiation and the resultant radiation doses to aircrew, passengers, and astronauts along with the possible resulting health effects and risks. This report …
Many resources are available that explain the basics of radiation, the risks of exposure, and planning considerations for hospitals, including Hospital Activities During Radiation Emergencies, from …
