Lunar-based measurements reveal Earth’s outgoing radiation is dominated by low-order spherical harmonics, providing unified global data for climate and environmental studies ...

Radiation Research, Vol. 57, No. 1 (Jan., 1974), pp. 88-103 (16 pages) Mouse testes were studied histologically 35 or 42 days after irradiation. When doses greater than about 800 rads of γ-rays are ...

Mary Helen Barcellos-Hoff of the New York University School of Medicine and colleagues exposed a group of 10- to 12-week-old mice to whole-body radiation at doses of 10–100 cGy. Three days later, they ...

Neutron activation analysis is a method for the qualitative and quantitative determination of elements based on the measurement of characteristic radiation from radionuclides formed by irradiating ...

Modern instrumental chemical analysis employs a variety of techniques. Fluorescence spectroscopy is one of these methods and is based on the principle of excitation and emission of characteristic ...

What The Study Did: Characteristics and response to treatment of persistent radiation-induced hair loss in patients with primary central nervous system tumors or head and neck cancer were examined in ...

The Effects of Radiation on Solids The orderly atomic arrangement characteristic of metals and other crystals determines many of their properties. Energetic radiation disturbs the order and thus can ...

Tsukuba, Japan—Scintillators convert radiation energy into light and are utilized in a variety of fields including medicine and security. Of the many scintillators, Eu (europium)-doped CaF₂ (calcium ...

Black holes are often described as cosmic traps from which nothing can escape, yet modern physics says they are not perfectly black. At their edges, quantum effects make them glow with a faint thermal ...
