Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Natural radioactivity radionuclides in building materials, such as Ra, Th and K, cause indoor exposure due to their gamma-rays. In this research, in a standard dwelling room (5.0 m × 4.0 m × 2.8 m), with the floor covered by various granite stones, was set up to simulate the dose rates from the radionuclides using MCNP4C code. Using samples of granite building products in Iran, activities of the Ra, Th and K were measured at 3.8-94.2, 6.5-172.2 and 556.9-1529.2 Bq kg, respectively. The simulated dose rates were 26.31-184.36 nGy h, while the measured dose rates were 27.70-204.17 nGy h. With the results in good agreement, the simulation is suitable for any kind of dwelling places.
