Sudah sebulan persidangan dan pameran ini berlalu. Baru hari ini tergerak di hati ku untuk menulis tentangnya. Alhamdulillah aku telah membentang satu kertas kerja seperti berikut;

Abstract

The design of X-ray or gamma ray radiographic exposure room requires some calculations on shielding to provide safe operation of the facility and minimum exposure to radiation workers. Careful design can lead to economical installations with minimal barriers. The design depends on such factors as: maximum energy, maximum intensity, permitted full-body dosage, workload, use factor, occupancy factor, maximum dose output and shielding materials. Choice of shielding materials depends on convenience and cost.  The radiographic exposure room is usually made of normal concrete with density of about 2.3 – 2.4 g/cc.  Normal concrete is often used for construction of exposure room because of cheap and ease of construction.

Labyrinth or maze type of design is the most popular especially for high energy radiation since it can reduce the radiation to a level that make the door design economic and practicable. 

This paper explained and discussed the distribution of radiation dose around the labyrinth type of exposure room.

Secara umumnya persidangan ini telah berjaya mengumpulkan ahli-ahli NDT seluruh negara. Bagaimanapun penyertaan agak kurang berbanding tahun sebelumnya. Begitu juga dengan kertas kerja. Tidak banyak kertas kerja ilmiah. 
Akan tetapi penyertaan untuk pameran cukup memuaskan. Banyak juga peralatan NDT dipamerkan. Barangan buatan China nampaknya semakin rancak dengan harga yang cukup berdaya saing.
