The purpose of this study is to improve a quick method for estimation of I concentrations in the air using data measured by monitoring posts in case that a nuclear disaster occurs. In this method, I concentrations were estimated by multiplying I count rates of cloud-shine measured with NaI (Tl) detector by concentration conversion factor. A previous study suggested that it was difficult to determine passing-through time of plume from temporal change of I count rates or dose rate. Our study applies the method for estimating passing-through time of plume from temporal change of noble gas counts. The I concentrations in the air at Oarai center, Japan Atomic Energy Agency resulting from the accident at the Fukushima Daiichi Nuclear Power Plant were estimated by proposal technique. The result of comparison of this method with sampling method for I concentrations in the air were within factor 3.

Measurements of the neutron capture cross sections of 
Am have been performed using a time-of-flight method with an NaI(Tl) spectrometer located on the ANNRI of the MLF in the J-PARC. The capture cross sections of Am were derived in neutron energies ranging from the thermal to resonance region. Comparisons of the present result with previous experimental data and evaluations were made. This contribution presents the obtained results.
