Laser Aid for Passive Night Sight Modification of Passive Night Sight of INSAS Rifle
Based on the user trial reports requesting for modifications in INSAS, the Laser Science & Technology Centre (LASTEC), Delhi, has modified the Passive Night Sight for INSAS Rifle System to facilitate accurate aiming by soldiers at night and help them reducing collateral damages caused during counter-insurgency operations. The pistol grip has been modified to house an electro-mechanical device (fabricated by LASTEC) and special power supply connector. A sophisticted laser head has also been miniaturised and fitted onto the sight toINSAS Rifle with modified Passive Night Sight improve the intensity of the laser spot at 50 m. An aluminium alloy laser head holder has been designed and fabricated to cater for maximum displacement (of 4 mm) in the lateral/vertical mode for lateral/vertical adjustments. The trigger has been integrated with the laser source and due to this the laser beam gets projected onto the target at the first pull of the trigger, and after firing when the trigger returns to the initial position, the system automatically switches off to minimise optical signature to conserve battery energy .The device has been successfully tested for 2000 operations. The modified rifles were up to the users satisfaction and were handed over to them on 27 November 2002.

INMAS organises International Conference on RaDIATion Damage and its Modification

Inaugural session of the conference In progress

The Institute of Nuclear Medicine and Allied Sciences (INMAS) , Delhi, organised the International Conference on RaDIATion Damage and its Modification during 12-15 November 2002. Dr VK Aatre, the Scientific Adviser to Raksha Mantri inaugurated the Conference at the LASTEC Auditorium, Delhi. About 150 scientists, including 20 from internationally reputed Institutes, participated in the Conference. Dr HC Goel,  Jt Director, INMAS and convener of the Conference, welcomed the delegates. Dr Jean Cadet, Scientific Adviser, Atomic Energy Commission, France, delivered the keynote address. Secretary of the Conference, Dr Madhu Bala, Sci E, INMAS proposed the vote of thanks.

The Conference resolved around the focal theme of raDIATion and biomolecule interaction, prophylactic modalities for radio-protection and management of post-irraDIATion injuries. Deliberations were initiated about the effect of raDIATion at molecular , cellular, tissue, whole organism, and population levels in a progressive way. Low-dose raDIATions effects and the biological dosimetric parameters were also discussed. The importance of herbal radio protectors was overweighing in comparison to molecular synthetic compounds.

The Conference concluded with a panel discussion chaired by Dr W Selvamurthy, Outstanding Scientist and Adviser, Biomedical Sciences and Dr HC Goel, Jt Director. The speakers, during panel discussion, emphasised on the need of international cooperation for development of radio protectors. The necessity of efforts for the development of herbal radio protectors was unanimously appreciated.
