The average city dweller or suburbanite is bombarded with a cacophony of sounds each day, and we all do our best to tune them out. Sustained exposure to noise levels greater than 70 dB can cause permanent hearing loss, and we’re routinely exposed to noises of over 100 dB near airports, construction sites, and other high-traffic areas. Excessive noise increases our stress levels, and it can also negatively impact workers’ productivity.

Utility companies have the power to raise rates as they see fit, and the only way to fight back is by reducing your energy consumption. This is often easier said than done, but you should start by identifying areas where energy is wasted.

When it comes to cancer, tumors, and other life-threatening illnesses, early detection is the key to ensuring the best possible clinical outcomes. Devices such as X-rays, CT Scans, and MRIs enable doctors and other diagnosticians to scan their patients without requiring them to go “under the knife,” and radiation therapy is an aggressive way to eradicate cancer in place of or in addition to chemotherapy. The health benefits outweigh the short-term risk of exposing patients to gamma radiation, but it’s crucial to protect the skilled technicians who operate the devices all day, every day!
