Ultra-trace determination of 90Sr, 137Cs, 238Pu, 239Pu, and 240Pu by triple quadruple collision/reaction cell-ICP-MS/MS: Establishing a baseline for global fallout in Qatar soil and sediments
(
Elsevier Ltd
, 2016 , Article)
The development of practical, fast, and reliable methods for the ultra-trace determination of anthropogenic radionuclides 90Sr, 137Cs, 238Pu, 239Pu, and 240Pu by triple quadruple collision/reaction cell inductively coupled ...
Natural and depleted uranium in the topsoil of Qatar: Is it something to worry about?
(
Elsevier
, 2013 , Article)
This study examines uranium in soils of Qatar to investigate whether there is any detectable traces of depleted uranium (DU). 409 soil samples were collected using a 10km grid system throughout the State of Qatar. The U ...
A market basket survey of As, Zn and Se in rice imports in Qatar: Health implications
(
Elsevier
, 2014 , Article)
Qatar is dependent on importation of rice, its staple dish, and is therefore susceptible to compromises of food quality in the global market. This market basket study assesses potential health risks of As exposure from ...
Ultra-trace Measurements of 210Pb in natural occurring radioactive materials by ICP-MS
(
Elsevier
, 2010 , Article)
Collision cell inductively coupled plasma mass spectrometry (CC-ICP-MS) was investigated as a possible alternative to nuclear analytical techniques for the determination of 210Pb. The formation of isobaric and polyatomic ...
