Cancer Doc Urges Cell Phone Precaution

the cellphone:

A prominent cancer researcher's warning to limit cell phone use has rekindled anew the longstanding question over mobile-phone health risks.

The media is abuzz with news of the memo from Dr. Ronald B. Herberman, director of the University of Pittsburgh Cancer Institute. He sent it to faculty and staff Wednesday, saying, among other things, that children should use cell phones only for emergencies, since their developing organs are the most likely to be sensitive to possible effects of exposure to electromagnetic fields.

In his 10-point advisory (see below), Herberman also urges adults to keep phones away from their heads and use speakerphones or wireless headsets.

He suggests that people try to avoid constantly carrying their cell phones on their bodies and also try not to keep the devices nearby at night under the pillow or on a nightstand. He even warns against using cell phones in public places like buses because it exposes others to the phone's electromagnetic fields.

Herberman notes that the precautions have been reviewed by UPCI experts in neuro-oncology, epidemiology, and neurosurgery, as well as the Center for Environmental Oncology.

The tumor immunologist's words are grabbing widespread attention both because of his professional position and because they contradict numerous studies that don't find a link between cancer and cell phone use.

Herberman said his warning was based on early findings from unpublished data.

"Recently, I have become aware of the growing body of literature linking long-term cell phone use to possible adverse health effects including cancer," he says. "Although the evidence is still controversial, I am convinced that there are sufficient data to warrant issuing an advisory to share some precautionary advice on cell phone use."

For anyone concerned about possible health repercussions of cell phone use, many of Herberman's suggestions are easy enough to implement and minimally disruptive at most. Still, the topic can prove daunting to consumers.

Practical Advice to Limit Exposure to Electromagnetic Radiation Emitted from Cell Phones

cell: Do not allow children to use a cell phone, except for emergencies. The developing organs of a fetus or child are the most likely to be sensitive to any possible effects of exposure to electromagnetic fields.

cell: While communicating using your cell phone, try to keep the cell phone away from the body as much as possible. The amplitude of the electromagnetic field is one fourth the strength at a distance of two inches and fifty times lower at three feet.

cell: Whenever possible, use the speaker-phone mode or a wireless Bluetooth headset, which has less than 1/100th of the electromagnetic emission of a normal cell phone. Use of a hands-free ear piece attachment may also reduce exposures.

cell: Avoid using your cell phone in places, like a bus, where you can passively expose others to your phone's electromagnetic fields.

cell: Avoid carrying your cell phone on your body at all times. Do not keep it near your body at night such as under the pillow or on a bedside table, particularly if pregnant. You can also put it on “flight” or “off-line” mode, which stops electromagnetic emissions.

cell: If you must carry your cell phone on you, make sure that the keypad is positioned toward your body and the back is positioned toward the outside so that the transmitted electromagnetic fields move away from your rather than through you.

cell: Only use your cell phone to establish contact or for conversations lasting a few minutes, as the biological effects are directly related to the duration of exposure. For longer conversations, use a land line with a corded phone, not a cordless phone, which uses electromagnetic emitting technology similar to that of cell phones.

cell: Switch sides regularly while communicating on your cell phone to spread out your exposure. Before putting your cell phone to the ear, wait until your correspondent has picked up. This limits the power of the electromagnetic field emitted near your ear and the duration of your exposure.

cell: Avoid using your cell phone when the signal is weak or when moving at high speed, such as in a car or train, as this automatically increases power to a maximum as the phone repeatedly attempts to connect to a new relay antenna.

cell: When possible, communicate via text messaging rather than making a call, limiting the duration of exposure and the proximity to the body.

cell: Choose a device with the lowest SAR possible (SAR = Specific Absorption Rate, which is a measure of the strength of the magnetic field absorbed by the body). SAR ratings of contemporary phones by different manufacturers are available by searching for “sar ratings cell phones” on the internet.

Attention: all Vegetarian Shepherds

the good shepherd:

Linda from (not sure) wrote:

"Hello there, many years ago I borrowed one of your cookbooks from the local library and cooked a meal that was reminiscent of shepherd's pie, but it used panir cheese and celery - well that is all I can remember. I have since bought one of your books but cannot find this particular recipe. I would be most grateful if you could steer me in the right direction or send me the recipe if you have it. By the way I love the rest of the book - your recipes give a whole new slant on vegetarian cooking. Kind regards, Linda."

My reply:

"Hello Linda, Thanks for your letter. Yes that's my famous vegetarian shepherd's pie recipe, perfected in the 1980's at Gopal's Restaurant in Swanston Stret, Melbourne. Here it is:"

veg shepherd's pie:

Vegetarian Shepherd's Pie

Those of you (like myself) of "Anglo-Saxon" background, will perhaps be familiar with the cruel, non-vegetarian origins of this dish. It contains the cooked minced flesh of slaughtered baby sheep {called 'lamb', by the way} which is smothered in mashed potatoes and baked in the oven. Here's my tender-hearted version.

PREPARATION AND COOKING TIME: 1 1/2 hours
YIELD: enough for 6 to 8 persons

For base of pie

1 1/4 cups brown lentils
2 litres water
2 tablespoons olive oil
1 teaspoon yellow asafoetida powder
1/4 teaspoon freshly ground black pepper
1 cup celery, diced
home-made curd cheese (panir) from (2 litres) milk and pressed for 1/2 hour, or 200g shop-bought panir cheese
5 tablespoons good quality tamari or soy sauce

For potato topping

2 tablespoons butter
6 large baking potatoes, peeled and cubed
1/2 cup milk
1 teaspoon salt
2 tablespoons sour cream
3 tablespoons chopped fresh parsley

Boil the brown lentils and water in a heavy 6-litre/quart saucepan. Reduce to a simmer and cook until they become soft. Strain through a colander. Put the lentils aside and retain the liquid for use as a soup stock at a later date.

Meanwhile, boil the potato cubes in slightly salted water until they become soft. Drain and mash them until smooth. Add the butter, milk, salt, and sour cream and mix well.

Heat the olive oil in a small, heavy pan until very hot. Add the asafoetida and pepper and saute momentarily. Add the celery bits and stir well; reduce the heat and braise the celery until soft, stirring occasionally. Remove from the heat.

Mash the drained lentils until smooth.

Crumble the curd cheese in a bowl and add the soy sauce. Mix well. Combine this mixture with the mashed lentils and the braised seasoned celery bits.

Spread this pie filling evenly in the bottom of an ovenproof casserole dish. Cover this with the mashed potatoes. Smooth the mashed potatoes and use a fork to mark the top with lines.

Bake in a very hot oven 230°C/450°F until the top is browned. Remove from the oven, sprinkle with fresh parsley, and serve hot.
