Levels of ionizing radiations in selected quarries in Nyamira County, Kenya.
Article in Heliyon, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
It has been shown through a survey by World Health Organization and International Commission on Radiological Protection that certain materials (stones) sourced from quarries and used for the building are radioactive. In Kenya, underground stones which are sourced from embedded rocks are used in construction of most of the permanent buildings, yet Kenya has not adequately radio-profiled sources of building materials to determine whether the construction materials contain radionuclides that emit ionizing radiations yet are used for building. Consequently, Kenyans could be at risk of exposure to high levels of ionizing radiations by living in stone houses that are not radio-profiled. Health problems arise due to subjection to ionizing radiations. The study determined the levels of ionizing radiations in sampled quarries in Nyamira County by using Radiological survey dosimeters to show the radiation readings in milliRoentgen/hr then converted to milliSievert per year and the Global Positioning System device took note of the quarries' geographical positions. The study used Minitab version 17.0 software to establish the statistical differences of degree of exposure in sampled quarries. The sample size for the study was 40 quarries. It was revealed that Q-073 and Q-075 both had the lowest radiation readings of 0.64mSv while Q-079 had the highest reading of 3.46mSv equal to a deviation from WHO approved threshold of -35.71%,-36.29% and 245.7%, respectively. The results indicated that 89% of the sampled quarries had radiation emissions above the ICRP and WHO standard. However, within Borabu Sub County, only 5 and within Manga Sub-County 4 of the sampled quarries had radiation readings below ICRP and WHO recommended standards of 1mSv/yr. It was exhibited from the study results that there are higher levels of ionizing radiations in quarries going past recommended standards per year hence causing health risk to quarry workers and general public. Therefore, these results could guide in formation of the national construction policies by including regular surveying for the levels of ionizing radiation in building materials as well as in practicing appropriate mitigation strategies.
