A year after Röntgen's discovery of X-rays in 1895, the American engineer Wolfram Fuchs gave what was probably the first radiation protection advice, but many early users of X-rays were initially unaware of the hazards and protection was rudimentary or non-existent. [11] The dangers of radioactivity and radiation were not immediately recognized.
Pregnant women are at higher risk of health issues from cadmium due to increased absorption of the metal during pregnancy. [17] Cadmium can also pose health risks to the fetus, some of which may be lifelong, as it interferes with placental function and fetal development. [18]
Supervisors at EPA's National Center for Environmental Assessment required several paragraphs to be deleted from a peer-reviewed journal article about EPA's integrated risk information system, which led two co-authors to have their names removed from the publication, and the corresponding author, Ching-Hung Hsu, to leave EPA "because of the ...
Bioenvironmental Engineers serve as emergency responders and health risk advisors for Chemical, Biological, Radiological, and Nuclear hazards, incidents, and their associated personal protective equipment (or clothing). BEEs are also HAZWOPER-certified, providing risk assessments and communication regarding hazardous materials.
Radiation exposure can be managed by a combination of these factors: Time: Reducing the time of an exposure reduces the effective dose proportionally. An example of reducing radiation doses by reducing the time of exposures might be improving operator training to reduce the time they take to handle a radioactive source.
Naturally occurring radioactive materials (NORM) and technologically enhanced naturally occurring radioactive materials (TENORM) consist of materials, usually industrial wastes or by-products enriched with radioactive elements found in the environment, such as uranium, thorium and potassium and any of their decay products, such as radium and radon.

The Toxic Substances Control Act (TSCA) is a United States law, passed by the 94th United States Congress in 1976 and administered by the United States Environmental Protection Agency (EPA), that regulates chemicals not regulated by other U.S. federal statutes, [1] including chemicals already in commerce and the introduction of new chemicals.
The MDA established a risk-based framework for the classification of medical devices and a regulatory pathway for medical devices to get to the market, created a regulatory pathway for medical device clinical trials, and established several post-market requirements including manufacturer registration and device listing with the FDA, good ...
