Radon and radium could pose serious risk to human health that is why our preliminary research was concentrated on their concentration in tap drinking waters from the Kavadarci municipality. We sampled three locations within city limits there have been determined radon concentrations respectively. of 0.53 Bq/l; 0.70 Bq/l 0,87 were for samples K1, K2 K3, respectively, which are 12 21 times less t...

Spent or disused sealed radiation sources—no longer needed sources—may represent a risk of radiological accident or may be a target for criminal acts in countries where final disposal options are unavailable and where an increasing number of sources are being kept in extended storage. In developing countries, thousands of radium needles, teletherapy sources, oil well logging neutron sources, an...

Hammctt (I), using the qualitative nitroprusside reaation, demonstrated the destruction of glutathione when water solutions were irradiated with p and y rays from radium. Woodward (2) confirmed Hammett’s observations quantitatively with radon, but failed to find any destruction with as high as 15,600 r units of Roentgen rays. She used the accurate titration method of Woodward and Fry (3) for ma...

A study is presented on the distribution of thorium and radium isotopes in sediments, suspended matter and water collected along Jucar river (East of Spain), using low-level CC-spectrometry. The first aim of this work is to study the thorium and radium activity in water, sediment and suspended matter and their dependence on pH, temperature, conductivity and sediment sizes along Jucar river. The...

2.2.2 (a) (ii) – 172 In first paragraph, last line, replace 222 Ra with 224 RA. 2.2.2 (b) (ii) – 173 In last paragraph, line 9, replace: [The Working Group noted that four cases of lymphoid leukaemia were found among people treated with radium, consisting of one acute and three chronic dysplastic leukaemias.] with: [The Working Group noted that four cases of lymphoid leukaemia were found among ...
