A NKS-B workshop on radioanalytical chemistry for radioecology and waste management was hold at Risø, Roskilde, Denmark in 16-20th November 2009. The workshop was organized as 3 days lectures and presentations and two days laboratory practice. 48 peoples participited the workshop, including 32 young participants from Denmark, Finland, Norway, Sweden, Lithuania and Ireland. This report gives a b...

In-situ and ex-situ measurements of environmental radioactivity were made on the iThemba LABS (iTL) grounds in South Africa. The MEDUSA and HPGe detector systems were used to make insitu and ex-situ measurements, respectively. The MEDUSA was mounted ∼0.5m above the ground on a 4× 4 vehicle to traverse [at ∼2m · s−1] the accessible portions of the iTL grounds. Spatial data (via a GPS receiver) w...

A long list of row materials are brought from the desert and invested in feeding of many industries. The investigation of radionuclides distribution and radiation levels of such materials is important to assess the potential hazard of radiation exposure for those working in such industries. In this work the high-resolution gamma-ray spectroscopic system was used to measure the radionuclides con...

Phosphate rock samples collected from the phosphate bearing formations of Sokoto State, Northwest Nigeria were assessed for their radiological contents by gamma spectrometric technique (sodium iodide (NaI (Tl) detector). The mean activity concentrations of 226 Ra, 232 Th and 40 K in all the studied samples were 720.1±4.2 Bqkg -1 , 33.5±1.4 Bqkg -1 , and 315.3±6.7 Bqkg -1 respectively. Contribut...

The study was conducted for the investigation of amount of radioactivity in the barren and cultivated soil of Bio saline Research Station in Pakka Anna, established by Nuclear Institute for Agriculture and Biology (NIAB) in 1990, 34 km. away from the city of Faisalabad, in the Punjab province of Pakistan. The studies were done on an area of about 100 hectares of two types of virgin and fertiliz...

This paper describes the most common presently used methods for detecting uranium and plutonium isotopes after their introduction to environment. Known isotope ratios of U Pu in different nuclear events are important tool characterizing sources material. Detection techniques both field laboratory presented, as well models that can be identifying origin age Identification source material environ...
