Gamma Ray Irradiation

This research used gamma ray irradiation on low doses (micro mutation). The aim of this research was to know the respons of doses level bymicro mutation on gamma ray irridation to the growing and development of Argomulyo variety of Glycine max (L) Merr (M1), the seeds isirradiated by gamma ray by micro mutation was 0 Gy, 50 Gy, 100 Gy, 150 Gy, and 200 Gy. Variation that obtained of each characters atgeneration M1 and M2 influences plants growth and development either through qualitative and quantitative that finally will influence plantsproduction. The average highest genetic variation at M 2 generation of soybean was on 200 Gy doses. Results of the research indicated thatgamma ray irradiation on 200 Gy doses was effective caused of plant variation genetic.

<p><a name="_Hlk39513249"></a><span lang="EN-US">Raja Bulu is one of the banana varieties favored by the community because of its thick fruit flesh and sweet taste. However, its parthenocarpic characteristic and vegetative propagation make this banana variety has limited genetic variation. Attempt to improve the genetic variation was conducted through induced mutation breeding using gamma-ray mutagens. This research aimed to select M1V1 generation of Raja Bulu banana (<em>Musa paradisiaca</em> Linn.) obtained by gamma rays’ irradiation for their growth traits which are expected to produce banana varieties that have an early maturity and high yield. This study used a randomized complete block design without replication by observing the generative growth of each individual of Raja Bulu banana irradiated by gamma rays and without radiation as a control. The results showed that gamma-ray irradiation treatment caused Raja Bulu banana to be harvested earlier and produced higher fruit weight than controls. The gamma-ray irradiation had a random influence on Raja Bulu bananas. The 10 Gy gamma-ray irradiation dosage influenced the morphological diversity in the generative phase of Raja Bulu banana. The treatment of gamma irradiation resulted in 5 individual plants that flowered and matured earlier as compared to controls</span><span lang="IN">.</span></p>

Right Ascension

A source of gamma rays has been found at right ascension 20h15m, declination +35°, with an uncertainty of 6° in each coordinate. Its flux is (1·5 ± 0·8) x 10-4photons cm-2sec-1at 100 MeV. Possible identifications are reviewed, but no conclusion is reached. The mechanism producing the radiation is also uncertain.

Low Altitude

AbstractThe experiment SONG (SOlar Neutron and Gamma rays) for the low altitude satellite CORONAS-I is described. The instrument is capable to provide gamma-ray line and continuum detection in the energy range 0.1 – 100 MeV as well as detection of neutrons with energies above 30 MeV. As a by-product, the electrons in the range 11 – 108 MeV will be measured too. The pulse shape discrimination technique (PSD) is used.
