Be concentration in the near-surface layer of the air in Bialystok (north-eastern Poland) in the years 1992-2010.

Weekly measurements of air Be concentrations (n = 769) were performed in the years 1992-2010 in Bialystok (north-eastern Poland) using gamma spectrometry. The arithmetic mean (AM) concentration of Be was 2.51 mBq m, and the median (M) was 2.

The use of 67Ga scintigraphy in patients with sarcoidosis.

Sarcoidosis is a systemic disease of unknown aetiology characterised by the formation of noncaseating granulomas in various organs and tissues. The various imaging modalities that are useful in the investigation of lesions, staging and establishing indications for treatment include: conventional radiography, CT, MRI, and scintigraphy with ⁶⁷Ga, ²⁰¹Tl, 99mTc sestamibi, and somatostatin receptor scintigraphy (SRS) as well as ¹⁸F-FDG-PET/CT. This paper discusses the most commonly used technique of the scintigraphic, gallium (⁶⁷Ga) citrate) and its role in the evaluation and monitoring of patients with sarcoidosis.

Radioactivity of natural medicinal preparations contained extracts from peat mud available in retail trade used externally.

In this work were identified and measured the activity of radioactive isotopes present in medicinal preparations from peat mud and estimated the doses obtained from them during therapy. Radioactivity of 22 preparations from peat mud and 20 water samples from water of the North-East region of Poland was studied. The median of the total activity was 24.

Radioactivity of peat mud used in therapy.

The aim of the study was to determine the contents of natural and artificial isotopes in peat mud and to estimate the radiation dose absorbed via skin in patients during standard peat mud treatment. The analysis included 37 samples collected from 8 spas in Poland. The measurements of isotope concentration activity were conducted with the use of gamma spectrometry methods.
