AI Article Synopsis
- The paper discusses the challenges of accurately measuring low levels of natural radionuclides due to variations in natural background radiation.
- The fluctuation in background can lead to discrepancies in determining the activity levels of both natural and artificial radionuclides.
- Results from experiments using shielded HPGe detectors are provided, highlighting how background fluctuation affects measurements and the minimum detectable activity (MDA) of radionuclides.
Article Abstract
The determination of low level activities of natural radionuclides from the uranium and thorium series by gamma-spectrometry faces the problem of proper natural background subtraction. Background fluctuation can cause differences in activity determination. Also the minimum detectable activity (MDA) of natural and artificial radionuclides can be influenced by background fluctuation. In this paper, results of the background fluctuation of shielded HPGe detectors with relative efficiency of 50-150% are presented together with the assessment of its influence on the determination of natural and artificial radionuclides.

Trends in the prevalence of Chronic Kidney Disease in the United States, 1999-2018.
Front Med (Lausanne)
January 2025
Department of Epidemiology, School of Public Health (Shenzhen), Sun Yat-sen University, Shenzhen, China.
Background: Chronic Kidney Disease (CKD) is an escalating public health concern in the United States, linked with significant morbidity, mortality, and healthcare costs. Despite known risk factors like age, hypertension, and diabetes, comprehensive studies examining temporal trends in CKD prevalence are scarce. This study aims to analyze these trends using data from the National Health and Nutrition Examination Survey (NHANES).

Background: Long COVID (LC) is a clinical syndrome with persistent, fluctuating symptoms subsequent to COVID-19 infection. LC has significant detrimental effects on health-related quality of life (HRQoL), activities of daily living (ADL), and work productivity. Condition-specific patient-reported outcome measures (PROMs), such as the modified COVID-19 Yorkshire Rehabilitation Scale (C19-YRSm) do not provide the health utility data required for cost-utility analyses of LC interventions.

Background: Inadequate energy intake among athletes can lead to low energy availability (LEA) which in turn can result in negative effects on athletic performance and physical and psychological health. This syndrome is known as relative energy deficiency in sports (REDs).
Objective: To map perceived changes in overall food intake among adolescent athletes during the previous year, as well as weekly changes during a 3-month period and to examine how these changes are associated with mental health, physical load and sex.

Natural Source Zone Deletion (NSZD) is a viable long-term management option for sites impacted by petroleum hydrocarbon fuels. NSZD rate estimation methods for petroleum mass losses often use soil gas gradients of oxygen, carbon dioxide, methane or vapour concentrations through the vadose zone. Seeking greater efficiencies, we investigated if existing short-screened wells are reliable for representative sampling of soil gases in a vadose zone undergoing NSZD.
