“Hello Priya…” Rajesh called his loving wife after a 10-hour stretch of work in a leading IT company in the city.
“Haaai darliinnng…” she responded in her usual loving tone, “how’zzz the day?” she asked.
“So hectic…” replied Rajesh in his tired voice.
“Ok dear. Have some drinks to cool yourself” she tried to relieve his suffering.
He sipped soft drink from the refrigerator and after a bath, he asked her, ‘Oh dear. What for dinner? Same thing today? Chappathi?’
“Take the dough from fridge’ she added.
After the dinner was over, he cleared the dishes from microwave and asked how her day was. “Lots of work still pending da… don’t know what to do!” Meanwhile, he switched the TV on to his favorite comedy channel Aditya and turned towards his wife. ‘Oh! God’, he exclaimed on seeing ‘401 WEB PAGE NOT FOUND’
Priya got frustrated thinking that Broadband service standards were still bad in India compared to the US on seeing the Rajesh’s profile in OFFLINE mode on GTALK!

Cobalt is a heavy metal well known for more than 300 years. Since all the forms of cobalt is highly unstable, no free form of it persists in nature. Cobalt is available in the form of ore.
40% of the world's cobalt comes from Zambia and Congo. There are many forms of isotope available for cobalt of which only Co60 has the longest half life of 5.27years. Artificial Co60 is created by bombarding a Co59 target with a slow neutron source, usually 252Cf moderated through water to slow the neutrons down, or in a nuclear reactor such as CANDU, where adjuster rods usually made of steel are instead made of 59Co.
Usually the Co60 used in medicine is produced in the size of 2 x 1.5cm cylinder. In India Co60 is produced by Board of Radio Isotope Technology(BRIT), Mumbai which supplies the cobalt source all over India and sometimes exports to foreign countries.
The supply and use of all the isotopes supplied by BRIT is supervised by Atomic Energy Regulatory Board(AERB). When a registered medical institute orders for the isotope with BRIT, it receives the total or part of the payment and place the orders with the Lab.
When the isotope is ready for delivery, the customer is informed to receive the source by paying the full amount(At present it costs Rs.40laks including transportation)The transport and loading process will be undertaken by the Teletherapy machine's manufacturer. The package will be packed in a lead shield and transported to the medical institute.
Under the supervision of the physicist authorized by AERB, the source loading will be done.
Since the half life of Co60 is 5.27 yrs it will emit radiation that can be used for treatment atleast for 10yrs. After that a new source should be purchased. While buying the teletherapy machine itself they will load the Co60 source,so 10 yrs after buying a new machine only, there will be need for source replacement.
The old decayed source will be taken back by AERB for safe disposal as per the guidelines of International Atomic Energy Agency(IAEA).Cobalt from radiotherapy machines has been a serious hazard when not disposed of properly, and one of the worst radiation contamination accidents in North America occurred in 1984, after a discarded cobalt-60 containing radiotherapy unit was mistakenly disassembled in a junkyard in Juarez,Mexico.
In Madras Medical College, the present machine is purchased in 1994 which is preloaded with the Co60 source which is now replaced after completing its third half life. Before that, a old form of teletherapy machine called Janus was used in which the source is loaded in the early 80s. SO its been more than 25 yrs for MMC to witness the source loading.

Starring: Premji Amaran, Jai, Vaibhav Reddy, Sneha, Paiaa Bajpai, Melony Mary
Guest Performance: Nayanthara, Simbu,
Director: Venkat Prabhu
Music: Yuvan Shankar Raja
Producer: Ocher Studio's Soundarya Rajinikanth
CBFC: Strictly A
Its a one line story. Three friends are going to Goa, enjoying the stay there. This one line theme is projected well on the screen with 14 reel of comedy and without logic.
Premji, Jai and Vaibhav were friends who run out of the village and heads to Goa in search of foreign girls and then fly abroad. These people are helped by two Gays. During their stay each one of them gets a girl of which premji make his dream of loving a foriegn girl.
The initial 20 minutes movie is superb. Definitely the city people will love those scenes. The cinematography is very nice, showing the beauty of Goa but should have explored Goa more instead of models. Though the doesnt have any logic, the love scenes of premji and mary were so touchable.
The worst part of the movie is the track played for Gay aspects. Dont no Tamil movie is turning into hollywood style now a days(But AVATAR has got many good old tamil sentiments)
Yuvan played his part well in rerecording but missed in playback except in goa song. No song remainds in mind.
Venkat Prabu didnt break his mind much. Just stealed the best part of all the tamil movies and used them appropriately.
Altogether leaving few minus GOA - Go to enjoy - Just 3 hrs journey.

The end of 20th century started facing a new kind of health problem in the form of CANCER. The word Cancer itself now turned into a worrisome issue. This disease is mostly due to the modern lifestyle and changing trends in the environment. Whatever the problem we face we ourself find the solution for that.
Yes. For cancer also we found many form of treatment, one of which is the RADIOTHERAPY and the branch of medicine that deals with it is the RADIATION ONCOLOGY.
When we hear the word radiation definitely ,we definitely tend to recall the incident happened to Japan in second world war through Nuclear bomb. Many incidents happened after that like Bokran Nuclear Tests, Bhopal Tragedy, Kalpakkam nuclear reactor, Famous Koodangulam Nuclear project and the famous Nuclear treaty signed by India with US followed with other countries too. Though we read this, hear this on medias, most of us are unaware of the fact that the same Radiation is used to treat the deadliest disease CANCER.
Ofcourse. From the day Roentegen discovered X-Ray followed by the treatment of Breast cancer patient by Dr. Gabreal supposed to be the first radiation oncologist, the miracles of Radiotherapy came to light.
Initially the Radiation treatment was done with the help of low energy X-Rays with out any proper gudelines and treatment protocols which added many side effects. In the early 1930's one institute in England started Radiotherapy department for the treatment of cancers followed by the Barnard Institute of Radiation Oncology in Madras Medical College which become the Asia's First premier institute to start the Radiotherapy department.
In the Late 1950's the X-Rays were overtaken by Cobalt-60 isotopes which made a revolution in the treatment of cancers all over the world. Later many isotope sources like Caecium, Iridium, Radium, etc., were introduced in radiotherapy which are used in different ways.
In the late 1980's a new form of machine called LINEAR ACCELERATOR was introduced which paved the way for hitech treatment planning reducing the side effects and improving the quality of life of people. The beginning of 21st century witnessed new innovations in the field of Radiotherapy like CYBER KNIFE, Intensity modulated radiotherapy, Image guided radiotherapy, Stereotactic radiosurgery etc.,
Radiation which is one of the cause of the cancer becomes the treatment for the same when properly planned and executed with proper radiation generators.
