Gemstone Irradiation and Radioactivity

2017-6-8  Exposure to radiation, either from natural or man-made sources, will enhance the color and beauty of many different gemstones. The use of man-made sources of radiation to treat gem materials was experimented with soon after radiation was discovered, almost 100 years ago. In recent years, gemstone irradiation has become a com-

Natural radioactivity levels and evaluation of

2018-10-1  Radiation exposure due to 226 Ra, 232 Th and 40 K may be external and defined in terms of external hazard index. To evaluate the external gamma (γ) radiation dose from ornamental stones, the following model was used as criterion. This model uses the external hazard index H ex defined as (Hayumbu et al., 1995).

Exposure to radiation from the natural radioactivity in

Abstract. The natural radioactivity due to the presence of 226 Ra, 232 Th and 40 K in selected building materials used in Jordanian building constructions has been measured using gamma-ray spectrometer with a Hyper Pure germanium detector. The average activity concentrations observed in different building materials ranged from 27.7 ± 7.5 to 70.4 ± 2.8, 5.9 ± 0.67 to 32.9 ± 3.9 and 30.8

Assessing exposure to granite countertops--Part 1:

Little information exists about radiation emissions and associated doses from natural stone finish materials such as granite countertops in homes. To address this knowledge gap, gross radioactivity, gamma ray activity, and dose rate were determined for slabs of granite marketed for use as countertops.
