With much slower cell reproduction cycle, roaches can withstand radiation, unless they are going through the ‘molting process’ or ‘exoskeleton growing phase’ when they are weak and vulnerable to the exposure with a high probability of fatality. Directly exposed to a nuclear blast, they succumb to intense heat. Why don’tRead More →
Adult: 5,000 Millirems. The current federal occupational limit of exposure per year for an adult (the limit for a worker using radiation) is “as low as reasonably achievable; however, not to exceed 5,000 millirems” above the 300+ millirems of natural sources of radiation and any medical radiation. Is Chernobyl safeRead More →
Gamma radiation sterilization is the most popular form of radiation sterilization. Co-60 and, to a lesser extent, Cs-137 serve as radiation sources and undergo decomposition to release high energy gamma rays. The produced electromagnetic radiation is highly penetrating and can kill contaminating microorganisms. Which radiation is used to sterilize surgicalRead More →
Conduction: Heat transfers into your hands as you hold a hot cup of coffee. Convection: Heat transfers as the barista “steams” cold milk to make hot cocoa. Radiation: Reheating a cold cup of coffee in a microwave oven. What are the 4 types of heat transfer? Various heat transfer mechanismsRead More →
